Question

All living cells are of the same shape and size.

• A. True
• B. False

Answer 1

The correct option is B False

Cells show great diversity in their shapes and sizes. The size and shape of a cell are related to its function. A nerve cell may attain a length of several meters while red blood cells are only 5-8µm in diameter. Also, within an organism, the cells rarely remain in the spherical form. They are either flat­tened (epithelial cells), spindle-shaped (muscle cells), spider-shaped (nerve cell), etc.
