which is correct
Answers
The Role of Transpiration Pull in Plants
This results in upward pull of water from the root to the mesophyll cells by generating a negative pressure in xylem vessels to pull the water from the soil. Transpiration pull in plants results from the evaporation or excretion of water from the surface of cells in the leaves.
Option B - Transpiration causes a suction pull
Explanation:
Transpiration is the method of water flow into a plant and its escape from aerial parts, such as petals, stems and buds.
Water is essential for plants but only a little quantity of water brought up by the roots is utilised for germination and metabolism.
The resting 97–99.5% is wasted by transpiration and guttation.
Leaflet covers are dotted with holes called stomata, and in most plants, they are more many on the foundations of the foliage.
Transpiration moreover cools shoots, alters osmotic strain of cells, and renders the core stream of metallic nutrients and liquid from rootlets to shoots.
