Biology Concepts

Biology is known as the study of life as it gives us a better understanding of living beings whether they’re visible to the naked eye or under a microscope. Students should have at least some basic knowledge about Biology because it will not only help them in their studies but also in medical or other entrance exams.

In our “Biology Concepts'' section, you will find all the important topics and subtopics, along with their definitions. From simple to complex concepts of different Biological Divisions like Botany, Biotechnology, Genetics, Ecology, Anatomy, zoology and more, our experts have paid utmost attention to explain all the key concepts.
