Question

Multicellularity brought about ___________ in the cells leading to increased efficiency.

• A. Simplicity
• B. Division of labour
• C. Maturity
• D. Behaviour

Answer 1

The correct option is B

Division of labour

Multicellular organisms are made up of millions and trillions of cells. All these cells perform specific functions. All the cells specialised for performing similar functions are grouped together as tissues in the body. Hence, a particular function is carried out by a group of cells at a definite place in the body. Similarly, different functions are carried out by different groups of cells in an organism and this is known as division of labour in multicellular organisms.
