D. No energy D.

Correct Answer: A সঠিক উত্তর: A

Explanation ব্যাখ্যা

Phloem transport requires a) ATP.
Active transport: The process of loading sugars into the phloem is active transport, which necessitates the use of energy from ATP.
Concentration gradient: ATP is used to move sucrose against its concentration gradient into the phloem cells, creating a higher solute concentration there.
Osmotic pressure: This high solute concentration then generates osmotic pressure, which drives the movement of water into the phloem, facilitating the transport of sugars throughout the plant.
