What is cell sap?

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

How does mineral salts enter roots?

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.

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.
