• B. Downward movement of organic nutrients
• C. Movement of contents in a vacuole
• D. Upward and downward movement of food materials

Answer 1

Answer: (A)

Upward movement of water and minerals in plants

Plants absorb water through the roots and transpiration takes place through leaves. Hence water moves from the root to the tip portion of the plant against gravity. This upward movement of water from the root to aerial parts such as stem and leaves is called ascent of sap. Thus the correct answer is option A.
