Answer 3

Why are simple animals called unicellular?

Simple animals are called unicellular because they are composed of only one cell. This means that all of their life processes, such as reproduction, digestion, and respiration, occur within a single cell. Unicellular organisms are capable of carrying out all of the functions necessary for life because they are structurally and functionally complete within a single cell.

The term "unicellular" is used to describe organisms that consist of only one cell, as opposed to multicellular organisms, which are made up of multiple cells that work together to form tissues and organs. Unicellular organisms are typically microscopic and include various types of bacteria, protozoa, and certain types of algae.

The classification of organisms as unicellular or multicellular is based on their structural and functional organization, with unicellular organisms being the simplest form of life in this regard.
