Discuss the mechanism of absorption of mineral salts by plant

Answer 1

Plants absorb the minerals from the soil and translocate them to other parts of the body. This process of absorption is facilitated by the roots in the form of ions. Soil clay contains crystals with a central nucleus called micelle which is negatively charged.

To maintain the balance, they hold positively charged ions on their surface. When this balance is disturbed by salt absorption, the equilibrium is again restored by transferring some of the absorbed ions into the solution. It is done by two different methods namely, active absorption and passive absorption.
