NEET 2023 Biology Solved Paper Code C4 (Manipur)

Statement I is incorrect but Statement II is correct.
Explanation :
Statement I is incorrect. The process of translocation in plants is bidirectional in phloem but unidirectional in xylem. Xylem primarily transports water and nutrients from the roots to the rest of the plant (upward direction), whereas phloem translocates sugars and other metabolic products from sources (like leaves) to sinks (areas of storage or growth, such as roots or fruits), which can be in either upward or downward direction.
Statement II is correct. Phosphorus, sulfur, nitrogen, and potassium are among the most readily mobilized elements in plants, especially during periods of nutritional stress. These nutrients are essential for plant growth and development and are actively translocated to areas where they are most needed.
