Question

What argument would you give for the necessity of a cell wall in plants, usually fixed in one place, versus in animals usually moving from one place to the other?

Answer 1

Plants are generally fixed in one place and cannot move around. To remain upright and withstand environmental factors such as wind and rain, they need a strong and rigid framework. The cell wall provides this strength, support, and rigidity, helping plant parts like leaves and flowers maintain their shape and firmness.

On the other hand, animals are capable of movement and therefore require flexibility rather than rigidity. Animal cells lack a cell wall, which allows them to change shape easily and adapt to various functions. This flexibility is essential for the movement and proper functioning of animal tissues. If animal cells had rigid cell walls, their ability to move and function efficiently would be greatly restricted. Thus, cell walls are important in plants for support and protection, while their absence in animals enables flexibility and mobility.
