Question
Give reason for the following:
It is better to transplant seedlings in a flower-bed in the evening and not in the morning.

Solution
Transplantation causes stress on the seedlings. If the seedlings are transplanted in the morning, they would have to immediately bear the additional stress of excessive transpiration occurring during the hot afternoon. Transplantation in the evening helps the seedlings adjust for a longer time during the night (cooler temperatures) because the quantity of water absorbed exceeds the loss of water through transpiration. Therefore, it is better to transplant seedlings in a flower bed in the evening and not in the morning.

- Osmosis
- Passive absorption
- The kind of force which exists between a liquid and any surface is called as:
- Cohesive force
- Adhesive force
- Capillarity
- Suction force
- The kind of force between the same kind of liquid molecules is:
- Capillary force
- Transpirational pull
- Adhesive force
- Cohesive force
- Sometimes exudation of water occurs from the margin of the leaves in the early morning or night. It is termed as:
