Question

Mineral ions diffuse out of the xylem vessels at the fine vein ending and are passively taken up by the cells.

• A. True
• B. False

Answer 1

The correct option is B

False

Mineral ions are diffused out of the xylem vessels at the vein endings. But these mineral ions do not enter the cells passively, instead are actively absorbed by the surrounding cells. Passive transport is through facilitated diffusion that does not require energy and active transport uses ATP or other energy sources for uptake.
