Tiny hair-like extensions that increase the surface area so that more minerals are absorbed.

Because the cell is underground and therefore cannot absorb sun light for photosynthesis which occurs in the chloroplasts.

What is the function of a red blood cell?
Flat and concaved,so that it has a greater surface area and can absorb more haemoglobin (oxygen) to transport to working muscles and other parts of the body.
