Question

the shape and size of the cells vary according to their function. justify

Answer 1

The shape and size of the cells vary according to their function. Cells become specialized to perform specific functions and exist in different shapes. They can be disc-shaped, polygonal, branched or without any fixed shape as seen in amoeba. 
Some examples are-

1. Nerve cells are elongated as they need to carry messages to different parts of the body.
2. Muscle cells are cylendrical and branched. They help in movement by contracting and relaxing.
3. Skin cells are flat in shape to produce a large surface area for covering the body for protection.
4. White blood cells can change their shape to help in destroying the germs in the body.
5. Sperm cells need to swim long distances, so they have a wiggly tail to propel themselves.
6. Cells in plants may be hexagonal, rectangular or spherical, depending on their functions.

(You can use any of the examples)
