(C) coated on both surfaces
(D) left uncoated.
All the four leaves A, B, C and D were left in a room for about 24 hours.
1. Which leaf would become most limp? Why?
2. Which leaf would show least limping? Why?
Answer:
1. Leaf D is very limp. Because this is the only leaf that is left untouched and water can be lost by switching up and down.
2. Leaf C shows a slight limping. Because both parts of the leaf are covered with Vaseline. Therefore, no water is lost from this leaf through transpiration.
