Question

Cell size and shape are related to cell function. Justify​

Answer 1

Answer:Hi!

The shape and size of a cell is indeed related to its function.

Explanation:

                    For example, the nerve cells are elongated in shape and are thin and dainty. This helps in transmitting the signals easily. Furthermore, the dendrites at the ends help transmit the messages to more than one other nerve cell so the message can reach either the brain or the spinal cord faster. The thin shape also helps keep the message on a straight path and keeps the message from getting confused or mixed up with other messages being transmitted so as to insure the direct and immediate receiving of all the messages.

We can also take the example of a simple animal cell. An animal cell does not have a cell wall. This makes it easy for it to move around the body. The red blood cells are also good examples of such a cell. It is round in shape so that it holds larger amounts of hemoglobin ( which contains oxygen ) for transportation all around the body.

Answer 2

Cell size and shape are related to cell function.

• Cell development occurs in such a manner in which the shape/size of the cell corresponds best to its function.

Lets take a few examples:

• RBCs (Red Blood Corpuscles) have bi-convex shape. This shape has least volume with highest surface area, hence helps to carry oxygen and deliver it to tissues.

• Similarly, sperm cells (male gametes) have an elongated, streamlined shape with a tail. This shape helps them to swim towards the ova and form a zygote.

• Similarly, neurons have an elongated axon with cellular protusions called dendrites. The dendrites take up impulses and the axon helps in transporting the electric impulse over long distances.

So, cell shape and size is related to cell function.
