Answer 1

$\textbf{Answer :}$
_______________

Yes, the shape and size of a cell are related to their specific functions.

In multicellular organisms,

A group of similar cell performing specific function form a tissue, group of similar tissue together form an organ, different organs work together to form an organ system. A group of organ system together make up an organism.

The cells are therefore designed in such a way so that they can perform that specific function.

for example,

♦ Nerve cells are elongated and branched, so that they can carry messages between different parts of body. A group of nerve cells together form a nerve, a group of nerve together form nervous system.

Whereas, in unicellular organisms a single cell is required to perform all the necessary funtions. Their body is designed in such a way so that they can carry those cells easily.

for example,

♦ Cell of amoeba is irregular in shape. This irregular shape helps the amoeba in movement and catching food, with the help of pseudopodia.

Answer 2

the shape and size of the cell are related to the specific function they perfom in following ways:

1 RBCs are biconcave in shape so that they can pass through varios places and help in exchange of gasses

2 WBCs are ameiboid in shape so that they can move to athin cappilaries and digest the froigein particle

futher nerve cell are long so that they can transfer impulse faster
