Question

Why there is no life without cell? Why cells are so smaller that we don't see them with our eyes? If they are big what happens?


Solution

Cells are the basic building blocks of all living things. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.
Cells are so small because, the important point is that the surface area to the volume ratio getssmalleras thecellgets larger. Thus, if thecellgrows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increasedcellularvolume.
