Active transport is dependent on____________?
Correct answer: B. Respiration
- A. Photosynthesis
- B. Respiration
- C. Photophosporylation
- D. None of these
Explanation
Active transport requires ATP to move substances against their concentration or electrochemical gradients, and plant cells mainly obtain this ATP through cellular respiration. Students may choose a because photosynthesis supplies energy-rich products in plants, but respiration is the immediate process that generates ATP for transport.
