Please help me!! Describe the effect of surface area and pores on cells.
ivanzaharov [21]

Explanation:

Surface area and pores play important roles in the cell.

Pores are the tiny holes on the surfaces of a body. They help to facilitate movement of materials in and out of the cell.

The surface area is the amount of space the surface of a cell occupies.

  • Pores in a cell needs to be in proper shape in order to facilitate movement of materials.
  • When the pores in a cell are too large, too much materials are bound to leave the cell. Tiny pores makes it difficult for the cells to have enough materials to function properly well.
  • The surface area of a cell allows for the diffusion of materials in and out of cell.
  • The larger the surface area of a cell, the more and better reactions takes place because they will receive important life sustaining resources.
