Question

Select the correct match regarding absorption and movement of minerals.

• A. Passive uptake – Slow, second phase of mineral uptake
• B. Efflux – Inward movement of ions into a cell
• C. Active uptake – initial rapid mineral uptake
• D. Apoplast – the movement of ions in the outer space of cells

Answer 1

The correct option is D

Apoplast – the movement of ions in the outer space of cells

The correct option is D.

Explanation of the correct option:

1. The apoplast pathway is the transport of ions across free spaces.
2. It is a passive transport and ensures the rapid movement of ions.
3. Hence, it does not consume any energy (in form of ATP).
4. It is found in plants where the movement of plants occurs into the xylem of plants in an upward direction.

Explanation of the incorrect options:

Option A:

1. Passive uptake is the diffusion process without the utilization of energy.
2. It occurs with the concentration gradient.
3. The uptake of minerals occurs from the concentration of a high gradient to the concentration of a lower gradient.

Option B:

Efflux transport occurs via special transport proteins which help to move proteins and cargo to the exterior of the cell.

Option C:

1. Active uptake is the movement of minerals across the cell membrane against the concentration gradient.
2. This process consumes ATP.

Final answer: The correct match regarding absorption and movement of minerals is apoplast which is the movement of ions in the outer space of cells.
