Question

Multicellular organisms have a division of labour. Explain

Answer 1

A tissue, organ, or organism composed primarily of too many cells is considered to be multicellular. Animals, plants and fungi are multicellular organisms.

Complete Answer:
Multicellular species consist of millions and trillions of cells. Many of these cells perform particular roles. Labor division refers to the separation of certain elements or parts to execute particular roles to improve the productivity and longevity of the organism. Almost all cells specialised in performing related roles are classified together as tissues in the body. As a consequence, a certain purpose is done by a group of cells at a certain position in the body. In the same way, various tasks are fulfilled by multiple combinations of cells in the body, and this is known as the division of labour in multicellular animals. Simply stated, in multicellular animals, the tasks important to the life of the organism are separated and assigned to various tissues and tissue structures. Both of these tissues and their structures function in a synchronised fashion.
For example, any cell of a multicellular organism couldn't get food from outside. The body needs a mechanism for the production, processing and delivery of food. The digestive system and transport system are therefore also needed. Thus, the tissues are responsible for feeding and transport. Similarly, muscles are used for excretion, respiration, etc. Similarly, certain cells of the body take over the purpose of reproduction. Others are involved in the restoration and reconstruction of worn or damaged parts. Thus the division of labour is demonstrated by multicellular organisms.

Note: Unicellular or single-celled species, on the other hand, are often much smaller in size and less complicated, since they are composed of one little cell that senses its atmosphere, collects nutrients and replicates asexually.
