Question

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

Accepted Answer

Unicellular organisms reproduce asexually while multicellular organisms may reproduce asexually or sexually.
Modes of reproduction in unicellular organisms-:
Some common asexual methods of reproduction in such organisms are as follows-
(i) Budding:
Yeast cells commonly divide by formation of an outgrowth (bud) which detaches and forms on maturity.

(ii) Binary fission:
It is one of the most common methods of vegetative reproduction in unicellular organisms such as Amoeba and most bacteria. In this method, the organism divides into two and each daughter cell develops into a new individual.
(iii) Multiple fission:
In some unicellular organisms such as Plasmodium, a single cell divides into multiple cells and each cell develops into a new Plasmodium.

Modes of reproduction in multicellular organisms:
i. Some of the common modes of asexual reproduction in multicellular organisms are fragmentation (Algae, Planaria), budding (Hydra), spore formation (Ferns) and vegetative propagation (in plants).
ii. Sexual reproduction occurs in higher plants and animals. They have complex body structure and hence have well-developed male and female reproductive sex organs which are to carry out sexual reproduction.
