Question

Which of the following is incorrect about transpiration?

• A. It causes transport of minerals.
• B. Excessive transpiration leads to water stress.
• C. Bleeding is caused by it.
• D. None of the above.

Answer 1

Answer: (C)

Bleeding is caused by it.

Transpiration leads to the establishment of water current in plants. The water current leads to bulk transport pathway for transport of water and minerals. Excessive transpiration will lead to water stress, which is visible as wilting of leaves. Bleeding is when sap leaks from a wound or pruning cut on a tree, shrub or woody climber. Sometimes, this may be a gentle seeping, other times a copious flow. Bleeding occurs due to the pressure of sap within the tissues that conduct water and sugars around the plant. Bleeding is not related to transpiration.
