Zoology

Zoology is the branch of biology which deals with the study of the animal kingdom including the structure, embryology, evolution, classification, habits and distribution of all animals, both living and extinct.

  • The whale is the largest living animal in the world.

Botany

botany is the branch of Biology, which deals with the study of plant life including their structure, properties, classification and biochemical process, both living and extinct.
