Question: What is semi-permaeable membrane?

Answer: Semi-permeable membrane is a cell membrane that allows only useful substances to enter the cell.

Question: What is cell sap?

Answer: Cell sap is a solution of concentrated sugars, mineral salts and other substances.

Question: How does mineral salts enter roots?

Answer: Mineral salts and other important nutrients enter the plant by a process known as active transport. This process uses energy.

Question: What is active transport?

Answer: Active transport is a phenomenon of movement of particles from lower to higher concentration with the use of energy, this energy comes from photosynthesis.

Question: How minerals salts are taken up?

Answer: Some mineral salts enter the roots by a simple process known as diffusion. Due to opposite concentration difference, some minerals move up the roots by a process known as active transport. Diffusion and active transport are opposite to each other.
