Question

How are the modes of reproduction different in unicellular and multicellular organisms?

Answer 1

Unicellular organisms are made up of only a single cell, in which all the functions are performed by the single cell. So, reproduction is done by simple, asexual methods but in multicellular organisms various cells perform different functions. So, production of all these specialised cells is required and simple methods for reproduction are insignificant. Thus, they reproduce by sexual reproduction.

Answer 2

Answer:

Modes of reproduction is different in unicellular and multicellular organisms.

In unicellular organisms, reproduction is by-

• Binary Fission as in case of Amoeba.
• Budding as in case of Hydra.

Reproduction in multicellular organisms is by giving birth.

Here, the female produces the egg or ova, which in turn, fuses with the male sperm, and form the zygote, which later on turn into a matured baby.

In unicellular organisms, only one sex is involved, but in multicellular organisms, both the sexes are involved.
