Question

Answer 1

Explanation:

Give reason the cell is called the structural and functional unit of life.

The cell is called the structural and functional unit of life as all living organisms are made up of cells. Cells are also essential for performing various life processes required for sustaining life. Furthermore, cells provide form and structure, process nutrients and convert it into useable energy.

Answer 2

Explanation:

if cells aren't so small,then not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function. That is why cells are so small.
