Question

11. Why is energy required to develop of root pressure?​

Answer 1

Answer:

Root pressure requires metabolic energy, which drives the (active) uptake of mineral ions from the soil into the root xylem. As ions accumulate in the root xylem, the osmotic potential of the xylem solution falls causing the passive uptake of water from the soil by osmosis into the xylem.

Answer 2

Answer:

hi frnd!!

Explanation:

Root pressure requires metabolic energy, which drives the (active) uptake of mineral ions from the soil into the root xylem. ... Water evaporates from the leaf surface into the atmosphere along this steep water potential gradient (no metabolic energy is required).
