photosynthesis

Answer 2

Option A is the correct answer.

• The transpiration procedure in plants establishes a suction pressure which pulls up water from the xylem of the roots to the stem and then to the leaf.
• Xylem tissues are in the structure of capillary tubes where the limited diameter, the enormous will be the pressure. Whenever the xylem vessels lay vacant, such as during the casualty of water by transpiration, the water from below increases into them by capillary pressure.

• Expected to transpirational snatch extra and more water molecules are pulled up due to their propensity of remaining enlisted. The pulling force established by the leaf is relatively significant in the possibility of tall plants where upward conduction of water carries position.

Hence, option A is the correct answer.
