A _____ force exists between the walls of xylem vessels and water. A. Cohesion B. Gravitational C. Adhesive D. Transpiration pull Process in which food substances are moved to rest of plant by phloem is known as A. Transpiration B. Translocation C. Respiration D. Photosynthesis Process/processes that does not require energy for movement of particles is/are A. Diffusion only B. Osmosis only C. Diffusion and Osmosis D. Active Transport

Solution

Amswer 31: Trans[irational pull: This is the force by which water molecules are interacting with the xylem cells and rising up in the plant.

Answer 32: translocation: is the peocess by which food substances reach different parts of plant from phloem.

Answer 33: Diffusion : This does not require any extra energy.
