NEET BIOLOGY

Detailed explanation-1: -Since unicellular organisms have only one cell present, when they divide, they give rise to two new cells, which can be considered a new organism. Each new cell is capable of performing all life processes by itself. So they can be considered a new individual. For example, amoeba divides by binary fission.

Detailed explanation-2: -We can consider cell division as a type of asexual reproduction in unicellular organisms because in the unicellular organism a single cell divides to form two identical daughter cells.

Detailed explanation-3: -Yeast is the unicellular organism which reproduces by budding.

Detailed explanation-4: -In unicellular organisms, cell division is important for reproduction only. They produce their daughter cells by the mitosis type of cell division. In multicellular organisms, cell division is important for producing new body cells and reproduction.

Detailed explanation-5: -In Monerans and Protists, cell division is itself a mode of reproduction. Example: Bacteria and Amoeba respectively.
