  • Animals could be unicellular like paramecium or multicellular like birds, fishes, 🐍, rabbit, human being. in addition, animal exists in a great variety of forms shapes and size.
  • The whale is the largest living animal in the world.


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.

  • Theophrastus is known as the father of botany.
  • Scientists have discovered more than 3,40,000 species of plants. Sequoia gigantea of California is the oldest and tallest plants of the world.
