Question

at night transport of water and minerals in plants occurs mainly due to the effect of
1)transpiration pull
2)root pressure
3)suction pressure
4)systolic pressure​

Answer 1

Answer:

2. root pressure

Explanation:

as root pressure occurs through the Xylem of the plant when it is humid (which is more at night than the day)

though, I am not so sure.. as I am learning plant biology for the first time but I think it is root pressure as it is what fits in theory mentioned

Answer 2

At night transport of water and minerals in plants occurs mainly due to the effect of root pressure.

Option - 2.

Explanation:

• Root pressure is a positive pressure applied by roots.
• The main job includes the transportation of water and minerals absorbed by roots, to the upper parts of the plant.
• However, the maximum activities of "root pressure" is seen at night.
• As because, during night evaporation is too low and transpiration is almost negligible.
• Thus, at night, "root pressure" is responsible for the "transportation of water and minerals".
