What Are The Characteristics Of Algae

What Is Biofertilizer – Microbes in Human Welfare – Biology Class 12

The special characteristics of algae are the same for both plants and animals. For example, algae can photosynthesize like plants, and they have specialized structures and cell organisms, such as centrioles and flagella, found only in animals. The general characteristics of algae are listed below.

  • Algae are photosynthetic organisms
  • Algae can be single-celled or multicellular organisms
  • Algae do not have a precisely defined body, and therefore do not have structures such as roots, stems or leaves.
  • Algae are found where there is sufficient moisture.
  • Reproduction in algae occurs in sexual and sexual forms. Spores are caused by fertilization.
  • Algae survive independently, although some can establish a spontaneous relationship with other organisms.

Ecology Biodiversity And Evolutionary Biology Specialization

A minor is not required for this major.

The Ecology, Biodiversity, and Evolutionary Biology specialization emphasizes ecological and evolutionary processes integrated with study of organismal diversity. Students will develop an understanding of the processes that influence relationships among organisms and interactions with their environments through selected courses and individual research projects. This program will prepare students for careers with government agencies , nongovernmental organizations, environmmental education groups, and the environmental industry. In addition, students will be prepared for graduate studies in fields such as ecology, evolution, animal behavior, natural resources management, or marine and aquatic biology.

Mode Of Reproduction In Algae

Algae reproduce by both sexual and asexual ways involving various reproductive strategies. Asexual reproduction occurs through normal cell division or fragmentation, without the union of two cells or without the combination of different genetic material in minor algae species. In the case of higher algae, reproduction occurs through spores. Sexual reproduction also occurs that involves the process of meiosis where genetic material from two different parent cells combines. Different environmental events influence and regulate sexual reproduction.

Read Effectively Read With Purpose

Reading biology to learn requires much more than skimming chapters or running your eyes over the pages looking for main points. Successful biology students attack each reading assignment with a pencil in hand, a notebook at their side, are actively engaged, and read with purpose. Every time you tackle a reading assignment, write down in your notebook important information, including vocabulary, processes, concepts and explanations. Writing things down helps to process and understand challenging material and improves retention. Your notes will also help you review for exams.

As you take notes while reading, write down the following:

  • TerminologyIt’s tempting to skip over unfamiliar terms and new vocabulary. Resist this temptation. Write unfamiliar terms and vocabulary down in your notebook and then look them up. This may seem tedious , but it is a necessary part of learning biology.
  • ConceptsRead the details, but read for meaning. After reading about a new concept, in your own words write down in your notebook a summary of the concept. Doing so will improve your understanding of the concept and provide you a valuable tool to prepare for your exam.
  • Diagrams and DrawingsWe can’t reiterate how effective it is to use diagrams and drawings to study biology. The same holds true when reading biology texts. Drawing pictures and developing diagrams to represent and describe the processes and systems you read about in your biology text will improve understanding and recall.

Human Digestive System Notes

Students in biology class
  • The human digestive system breaks down food to release energy essential for the body to carry out its activities.
  • The process of digestion takes place in 6 major steps.
  • The food is ingested by the alimentary canal and is propelled through the body for further processing.
  • The autonomous nervous system controls the peristalsis, contraction and relaxation of muscles within the alimentary canal wall.
  • The food is passed to the small intestine where it is digested, and the nutrients are absorbed.
  • Water, electrolytes and vitamins are absorbed by the large intestine and the waste is defecated.

We Still Arent 100% Sure Why People Yawn

Many scientists today think that yawning is a way to keep our brains alert in times of stress, but exactly why that happens or what the yawn does to help our body isnt 100% clear. That could be why they are contagious we are alerted to a potential stressor by another person. Others believe that yawns are a reaction to being tired, as a way to reengage. Yawning may help us get more oxygen to help our brains perform better, or it may cool down the brain, which gets hotter in times of stress. We still arent exactly sure what role yawning serves in human biology.

Our Appendix Does Actually Still Have A Purpose

We have long thought that the appendix was simply the result of evolutiona body part that once had a purpose, but that no longer does anything other than occasionally get infected.

Research has revealed, though, that the appendix actually serves as an important place for the bacteria in the digestive system to rest and reproduce. You can definitely live without it , but when its still a part of your system, the appendix can be a real help.

Roots Of Human And Social Biology

The pioneer of human and social biology is Edward Osbourne Wilson who initiated its study through his book, Sociobiology: The New Synthesis . Based on the evolution theory, sociobiologists observe that mans natural tendencies are often hinged on his anatomical fixtures, which have evolved over the course of millions of years. Based on these observations, sociobiologists have compared animals biology and society with mans. They have seen glaring associations that prove the universality of sociobiology.

The Human Digestive System

The digestive system of the human body comprises a group of organs working together to convert food into energy for the body. Anatomically, the digestive system is made up of the gastrointestinal tract, along with accessory organs such as the liver, pancreas and gallbladder. The hollow organs that make up the gastrointestinal tract include the mouth, stomach, oesophagus, small intestine and large intestine that contains the rectum and anus.

Human Digestive System and Nutrition involve the intake of food by an organism and its utilization for energy. This is a vital process which helps living beings to obtain their energy from various sources. The food which we eat undergoes much processing before the nutrients present in them are utilized to generate energy. This processing is known as digestion. Humans and other animals have specialized organs and systems for this process.

The digestion process involves the alimentary canal along with various accessory organs and organ systems. In humans, the process is quite simple due to our monogastric nature. This means that we have a one-chambered stomach, unlike other animals such as cows, which have four chambers.

Some parts of nervous and circulatory systems also play a significant role in the digestion process. A combination of nerves, bacteria, hormones, blood and other organs of the digestive system completes the task of digestion.

Allows Transport Of Substances

Various nutrients are imported by the cells to carry out various chemical processes going on inside the cells. The waste produced by the chemical processes is eliminated from the cells by active and passive transport. Small molecules such as oxygen, carbon dioxide, and ethanol diffuse across the cell membrane along the concentration gradient. This is known as passive transport. The larger molecules diffuse across the cell membrane through active transport where the cells require a lot of energy to transport the substances.

What Is The Importance Of Algae Economic Importance Of Algae

These eukaryotic marine organisms have no roots, flowers or twigs. It plays an important role in the recovery of alkali used as a soil binding agent. They are economically important in various ways as discussed below:

  • Diet: Algae are rich in carbohydrates, fats, proteins, vitamins A, B, C, and E as well as iron, potassium, magnesium, calcium, manganese and zinc. Therefore, people in Ireland, Scotland, Sweden, Norway, North and South America, France, Germany, Japan, and China use it as a food ingredient.
  • Fodder: Algae are used as fodder to feed livestock and livestock. It is used as a grain in various countries including northern European countries such as Denmark, Sweden and Norway.
  • Fish farming: Algae play an important role in fish farming as it helps in the production process. Fish used plankton and plankton as food. This helps maintain the health of the marine habitat, as algae naturally absorb carbon dioxide and provide oxygen to the water.
  • Fertilizers: Algae are rich in minerals and vitamins. Therefore they are used as a liquid fertilizer, which helps to improve the amount of nitrogen contained in the soil.
  • Alkaline recovery: Blue-green algae help reduce high levels of alkalinity in the soil.
  • Binding factor: Algae act as a binding agent against natural processes such as erosion.
  • Biological Indicators: Algae are very sensitive, their pigments can change or die if there is even a slight change in the environment.

Disorders Of The Human Digestive System

Human Reproduction

Vomiting: It is the ejection of stomach contents through the mouth.

Diarrhoea: It is the abnormal watery bowel movement. Prolonged diarrhoea eventually leads to dehydration.

Constipation: A condition in which the faeces are clutched within the rectum due to an irregular bowel movement.

Indigestion: A pain or discomfort in the stomach which is caused when food is not digested properly, resulting in the feeling of fullness. Indigestion is mainly caused due to inadequate enzyme secretion, food poisoning, anxiety, overeating and eating spicy foods.

Structure Of The Heart Wall

The heart wall is made up of 3 layers, namely:

  • Epicardium Epicardium is the outermost layer of the heart. It is composed of a thin-layered membrane that serves to lubricate and protect the outer section.
  • Myocardium This is a layer of muscle tissue and it constitutes the middle layer wall of the heart. It contributes to the thickness and is responsible for the pumping action.
  • Endocardium It is the innermost layer that lines the inner heart chambers and covers the heart valves. Furthermore, it prevents the blood from sticking to the inner walls, thereby preventing potentially fatal blood clots.

Functions Of The Human Digestive System

Digestion and absorption are the two main functions of the digestive system.

Digestion is necessary for breaking down food particles into nutrients that are used by the body as an energy source, cell repair and growth.

Food and drink need to be converted into smaller molecules of nutrients before it is absorbed by the blood and carried to the cells throughout the body. The body breaks the nutrients present in the drinks and food into carbohydrates, vitamins, fats and proteins.

The Brain Works Harder While We Are Asleep Than During The Day When We Are Awake

What Is Bacterial Biofertilizer – Microbes in Human Welfare – Biology Class 12

Many people assume that sleep helps the brain rest, but our brains are actually busier during slumber. When we sleep and dream, our brains carry out important functions that they cannot perform while focusing on movement and conscious thought. During sleep, our brains process things we learned and emotions we felt during waking hours and saves them in our memory. Thats why sleep is so important to learning.

Go From General To Specific

Anyone can learn biology, but it’s not always easy. Biology doesn’t require as much math as physics or astronomy, but it can still be challenging to understand biological systems and processes. One of the keys to effective learning of biology is to master general concepts before tackling specific ones. For example, before you can understand the Krebs cycle you need to have a basic understanding of animal cell structure. Study each new biological concept and process thoroughly before moving on to the next level.

Learn How To Memorize


Biology is the basis of so many of the natural sciences and covers a myriad of topics from osmosis and diffusion to homeostasis and cell biology to virology and immunology. It is truly one of the most diverse subject areas taught at any high school or major university. As such, the study of biology requires a lot of retention, recall, and memorization of information. The following are proven tips for memorizing information as you study biology.

Origin Of The Term Biology

Before the term biology was adapted, other terms existed which described the study of plants and animals. For instance, the term Natural History was used to explain animals, plants fungi and other lifeforms in their natural environment.

Furthermore, it was observational rather than an experimental field of study. Hence, a person who would study natural history is termed as a natural historian or a naturalist. Other terms that came before biology included Natural Theology and Natural philosophy.

The term Biology, in the modern sense, was introduced through the works of Michael Christoph Hanow in 1766. However, it was introduced independently four more times through the works of Thomas Beddoes , Karl Friedrich Burdach , Gottfried Reinhold Treviranus and Jean-Baptiste Lamarck .

What You Will Study

The bachelors of science in biology with human biology specialization is designed for a diverse group of students from future laboratory technicians to students interested in direct entry masters of nursing programs.
