Question

Why most of the tissues in animals are living ?

Answer 1

Living tissues

1. Cells in the tissues can be dead or living.
2. Dead cells do not contain protoplasm and cell organelles and usually occur in plants to provide mechanical strength and support.
3. Living cells contain protoplasm and carry out various functions with the help of their organelles.

Animal tissues

1. Animals move from one place to another in search of food, shelter, and mate, so they require more energy for their functions and maintenance.
2. Animal tissues are made up of living cells containing protoplasm because they require more energy for their body activities.
