Locomotion
- Flagella plays a vital role in the movement of euglena.
- It also shows euglenoid movement or metabolic in which it betrays a slow worm-like movement by alternate contraction and expansion of the body.
- It shows phototaxis movement, i.e, responds to light or stimulus of light.

Biological classification is a scientific plan that consists of arranging organisms into taxonomic groups and subgroups based on their similarities and dissimilarities. The word Biology was first coined by Lamarck and Treviranus in 1802. It is mandatory to classify organisms for numerous reasons. Aristotle was the first scientist to take a step toward the classification of organisms.
Cells are one of the most crucial features of living organisms, as they are the building blocks of life. They perform particular functions. All of these cells join to form a tissue. There are plenty of living organisms present in this world. Mega biodiversity regions are those which are humid and warm because they provide the optimum temperature and nutrients for the development of species. Two kingdom system was proposed by Linnaeus, which includes Plantae and Animalia kingdoms. The five-kingdom system was proposed by R.H Whittaker in 1969 which included Monera, Protista, Fungi, Plantae, and Animalia kingdoms.
