Biology
Biology is the branch of science that deals with life and living organisms. The main objective of Biology is to understand the various processes taking place inside any living organism. It includes the formation of cells, composition of cells and formation of tissues. It also reflects on the changes occurring in human body. It depicts how the living and non living components interact with each other.
Here we will cover the various topics regarding Biology for Class 9. The concepts that are mastered in the lower classes help us to crack many entrance examinations like NEET, AIIMS, AIPMT, UPSC etc. At ABHYASONLINE.IN you can master the concepts at your own learning pace. It provides conceptual testing with analytical reports identifying the weak, moderate and strong concepts. We, at ABHYASONLINE.IN believe that, if the weak concepts are timely identified and improved, then every student can achieve their goals in life. Follow the links below to understand and master each and every concept of various topics in Biology along with video lectures.

In biology, a tissue is defined as a group of cells with similar structure, organized to do a common function. A tissue is a group of similar cells and their extracellular matrix to carry out a specific function. Organs are then formed by the functional grouping of multiple tissues. In this section topics of Plant Tissue such as Permanent Tissue, Parenchyma, Collenchyma, Sclerenchyma, Epidermis, Phloem Xylem, etc. have been explained. Watch the videos and master the concepts

The biological world consists of many diverse species. There are so many varieties that it is almost impossible to study all of them in a single life span. Organisms have been grouped together on the basis of their features .In this section of diversity of living organism Classification, Classification depending on evolution, Taxonomic hierarchy, Taxonomy, Algae, Angiosperms, Animalia, Bryophyta, Charles Darwin, Fungi, Gymnosperms, Hornworts, Liverworts, Monera, Monocotyledons and Dicotyledons, Mosses, Plantae, Protista, Pteridophyte etc. have been explained.

In biology, the removal of metabolic waste products from the body of an organism is known as excretion. The major excretory products are Carbon dioxide, excess water, and nitrogenous compounds like ammonia, urea, uric acid, etc. In this section of Life Process Excretion in Animals, Excretion in Plants, Excretion Meaning, Excretion through Skin Liver and Lungs, Hemodialysis and Dialysis, Human Excretory System, Process of Excretion in Nephron, Structure of Kidney, Structure of Nephron etc. have been explained.
