Which of the following statement about cells is true?

Options

A. All the cells have nucleus.
B. All cells are round in shape.
C. Cells of a tissue have similar structure.
D. Size of cells is same in a well organised organism.

Answer

C

Explanation

Cells of a tissue have similar structure, this statement is true, Other statements are wrong because cells vary in their shapes. They can be polygonal, disc-like amoeboid, thread-like, cuboid or irregular. Since, cells in plants and red blood cells in humans do not have nucleus and size of cells is not same in a well organised organisms.
