Detailed explanation-1: -Cells show great diversity in their shapes and sizes. The size and shape of a cell are related to its function. Some multicellular organisms may have smaller sized cells as compared to many unicellular organisms. Some single cells like the eggs of birds and reptiles are quite large.

Detailed explanation-2: -Cell size varies depending on where it comes from and what it does. This means that a bacterial cell is smaller than an animal cell, a human red blood cell is smaller than a human nerve cell and all of these are smaller than the single-‐celled, 15cm long ostrich egg!

Detailed explanation-3: -Although all living cells have certain things in common-such as a plasma membrane and cytoplasm-different types of cells, even within the same organism, may have their own unique structures and functions. Cells with different functions generally have different shapes that suit them for their particular job.

Detailed explanation-4: -The statement that All cells are of the same size and shape is False.

Detailed explanation-5: -Surprisingly enough, each of these cells varies in shapes and sizes. There are several different groups of cells which perform a plethora of functions. Every organism that has more than one cell is known as the multi-cellular organism.
