Biology, the study of life itself, is a vast subject, with many sub-disciplines that concentrate on specific aspects of biology. Microbiology, for example, concentrates on those biological processes and structures that are too small for us to see with our eyes. Biochemistry studies the chemical processes that make life possible and population biology deals with the dynamics of many life forms interacting in a community. Since biology is such a vast field of inquiry, most biologists end up specializing in one of these subdisciplines. Nevertheless, before you can begin to specialize, you need a broad overview of the science itself.
Properties of Carbon
Did you know, carbon is the second most abundant element in humans (about 18% of mass) after oxygen? Explore more about this element and the reason behind its importance in biological elements.
Food provides the body with the nutrients it needs to survive. Many of these critical nutrients are biological macromolecules, or large molecules, necessary for life. Four main types of macromolecules such as proteins, carbohydrates, nucleic acids and lipids control all activities. Explore the types of macromolecules,
Their importance in human life and how they are build up.
Energy and Enzymes
Several chemical reactions are taking place in the body of a living organism and surprisingly all of them are mediated by enzymes. Read more about how energy transfers occur in a human body and how biological energy transfers work and much more.
Structure of a Cell
Do you know, humans have about 100 trillion cells in their body! All the living organisms that exist in this whole universe – like mushrooms, plants, humans, elephants etc. are made up of lots and lots of cells! Learn more about different types of cells, their structure and much more.
Membranes and Transport
This Topic is all about how cells protect themselves from the surrounding with a barrier. Explore more about what this barrier is made up of, how it works and how the molecules are transported across the membrane.
Respiration is one of an essential process carried out by all living organism to survive. Explore more about how it extracts energy from food for the human body, how respiration occurs at the cellular level, its types and much more.
Did you know photosynthesis is the single most important chemical process on the earth? Learn more about how plants utilise sunlight to convert light energy to chemical energy, Calvin Cycle, light-dependent reactions and much more.
Did you know in an average human body almost 2 trillion cell divisions occur on a daily basis? Every organism goes through cell division process. So let’s study about how cell division occurs and how the problem in cell cycle control is responsible for causing cancer.
Classical and Molecular Genetics
Know about the reason behind the resemblance of children to their parents, the impact of genetics on the next generation and explore more about Mendel’s model of inheritance, it’s disorders and much more.
DNA as the genetic material
Did you know your DNA could stretch from the earth to the sun and back approximately 600 times? Explore more facts about DNA, its structure and much more.
Did you know we have tens of thousand of genes in our genome? Read more about what is gene regulation and how it controls the manner and rate of gene expression.
Did you know humans have unknowingly used biotechnology practices for thousands of years, specifically in pharmaceuticals and farming? Explore more facts about biotechnology, its application and its scope in agriculture.
History of life on Earth
The first life on Earth developed in the oceans through a process called abiogenesis or biopoiesis. This is a natural process in which life grows from nonliving matter like simple organic compounds! Explore more about life on earth.
Ecology encompasses all living things, from single-cellular and acellular organisms, through to the most complex of all living creatures. Read more about ecology, population ecology, types of biogeochemical cycles and much more.
Biodiversity and conservation
Biodiversity is very important to an ecosystem because each species plays a different role in the maintenance of the ecosystem. Discover more about the ecosystem and ecosystem services and much more.
The human body is an amazing system as it is made up of a group of organs called organ system. Explore more about the organ systems starting from circulatory system to nervous system and much more.
Learning biology could be a hard job if you don’t create an effective method to memorize the hundreds of terminologies and definitions involved. At Byju’s, we provide you with video lessons that contain an elaborately animated representation of the actions and reactions of the Biological world. Once you watch these videos and understand the occurrences of the Biological world, it will become impossible for you to forget those.
Starting from class 6 with the explanations regarding food , the living organisms, etc up till the much more interesting topics in Botany and Zoology taught in class 12, like principles of inheritance and variation, evolution, reproduction in organisms, etc, Byju’s provide very interesting sessions of video classes taken by experts in the area. You can engage yourself with interactive video sessions, regular tests prepared by our experts, continuous analysis based on your performance and much more by getting Byju’s learning app.
