Q. Consider the following statements regarding transported substances in plants:- The process of translocation in phloem is driven solely by simple physical forces.
- The transfer of materials like sucrose into phloem tissue requires energy obtained from ATP.
Which of the above statements is / are correct?
Answer:
Only 2
Notes: Unlike xylem, which primarily uses physical forces such as transpiration pull, phloem translocation is an active process. The loading of sucrose into phloem tissue utilizes the energy from ATP, making statement 2 correct. Statement 1 is incorrect as physical forces alone do not drive phloem translocation.
