LIFE SCIENCE

Detailed explanation-1: -In all complex multicellular organisms (eukaryotes), cell duplication occurs by a process called “mitosis” or cell division.

Detailed explanation-2: -Mitosis is important to multicellular organisms because it provides new cells for growth and for replacement of worn-out cells, such as skin cells. Many single-celled organisms rely on mitosis as their primary means of asexual reproduction.

Detailed explanation-3: -In the case of multicellular organisms, mitosis helps in growth and repair by producing more number of identical cells. For example plants, animals depend on cell division for their growth by addition of new cells.
