Question

What is the significance of tissues in multi-cellular organisms?

• A. Tissues are a specialized group of cells.
• B. Tissues carry out specific functions very efficiently.
• C. Tissues impart the advantage of division of labour.
• D. Organisms become more complex and can utilize the environment much better due to tissues.

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A Tissues are a specialized group of cells.
B Tissues carry out specific functions very efficiently.
C Tissues impart the advantage of division of labour.
D Organisms become more complex and can utilize the environment much better due to tissues.

In multi-cellular organisms, different types of tissues perform different functions. Since a particular group of cells carries out only one particular function, they do it very efficiently. So, multi-cellular organisms possess a definite division of labour. Due to this great property, organisms evolved and became more complex in order to adapt to the changing environment in a better way. Thus, tissues also have an evolutionary significance.
