LIFE SCIENCE

Detailed explanation-1: -Multicellular organisms consist of more than one cell. They performed sexual reproduction in which gametes form by mating two individuals. The lifespan of multicellular organisms is long as compared to unicellular ones.

Detailed explanation-2: -Multicellular organisms are larger, more efficient, and have a longer lifespan than unicellular organisms. Multicellular organisms need more resources than unicellular organisms. The cells are specialized and must depend on each other for survival of the organism.

Detailed explanation-3: -Multicellular organisms have a higher chance of survival due to the division of functions to various cells and advanced reproduction process while unicellular face the risk of extinction due to parent cell loss caused by cell division.

Detailed explanation-4: -The unicellular organisms are immortal, as they are capable of regeneration whereas multicellular organisms lose the regeneration ability for cell growth and differentiation of cells aging.
