Question

(a) Are the cells in an elephant larger than the cells in a rat?

(b) What are the different shapes of cells?

Answer 1

(a) The size of the cells has no relation with the size of the body of the animal or plant. It is not necessary that the cells in the elephant be much bigger than those in a rat. The size of the cell is related to its function.

(b) Generally, cells are round, spherical or elongated. Some cells are long and pointed at both ends. They exhibit spindle shape. Cells sometimes are quite long. Some are branched like the nerve cell or a neuron.
