Discussion Forum : Transport In Plants
Question - Mineral ions diffuse out of the xylem vessels at the fine vein ending and are passively taken up by the cells.
Options:
A .  True
B .  False
C .  The RBC would increase in size and burst while the plant cell would remain about the same size
D .  The plant cell would increase in size and burst while the RBC would remain about the same
Answer: Option B
:
B
Mineral ions are diffuse 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 facilitates diffusion that does not require energy and active transport uses ATP or other energy sources for uptake.
