At night, transport of water and minerals in plants occur mainly due to the effect of ?
Answers
the water molecules travels through plant and water is evaporated from the surface of leaves. Along with the loss of water vapour in transpiration exchange of carbon dioxide and oxygen also occurs in the pores of stomata. These stomata are open during day and closed during night
Answer:
The correct answer will be- root pressure generated in response of the absorption of ions in xylem.
Explanation:
Root pressure is the pressure generated in the xylem of the plants sue to the accumulation of the solute particle which decreases the water concentration in the xylem.
The root pressure is responsible for the uptake of water mainly during the night as the evaporation of water is not observed during the night which leads to no transpiration pull.
This generated root pressure although not strong to move the water too long height but they help uptake the plants to take water from the soil during the night.
Thus, root pressure is the correct answer.
