Question

In the ringing experiment when phloem tissues are removed, we observe swelling on the upper part of the ring. This is due to:

Options

• Accumulation of water

• Healing of the cut part

• Accumulation of sugars that are not translocated

• None of these

Answer 1

Accumulation of sugars that are not translocated

Explanation:

We observe swelling on the upper part of the ring due to the accumulation of sugars that are not translocated because removing the outer phloem layer blocks the downward path, causing the food coming from the leaves to pile up right above the cut.
