Question

The process by which minerals get absorbed is

• A. Active absorption
• B. Passive absorption
• C. Guttation
• D. None of the above

Answer 1

Answer: (A), (B)

The correct options are
A Active absorption
B Passive absorption

The minerals are mainly absorbed by roots that are in direct contact with the soil. Absorption of water is known as water uptake. Short distance transport of water takes place from cell to cell across the membranes involving physical processes such as diffusion, osmosis and water potential differences. Long-distance transport involves complex processes such as root pressure and transpiration pull. transport There are two processes by which mineral absorption takes place:

1. There is rapid uptake of ions into the outer free surface passively down the gradient of electrochemical potential energy.

2. The movement of ions into the inner space requires the expenditure of energy and is called active uptake.

Thus, the correct answer is option A and B.
