Question 2
What is the significance of tissues in multi-cellular organisms?

Answer 1

In multi-cellular organisms, different types of tissues perform different functions. So, multi-cellular organisms possess a definite division of labour. Tissues have a specific and destined function which they do very efficiently. 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.
