Q584

When half the leaves are removed randomly, transpiration will show

A.
Lower magnitude but higher flux
Answer
B.
Higher magnitude but lower flux
C.
Both magnitude and flux increase
D.
Both magnitude and flux decrease

Answer: Option A

Solution

Answer: Option A
Solution:
When half the leaves are removed randomly, transpiration will show lower magnitude but higher flux.
Less number of leaves offers less opportunity for transpiration, therefore the rate of transpiration will be lower on magnitude but flux is higher.
Transpiration (T) is the flux of water vapour and latent energy returned to the atmosphere by vascular plants, mainly through the stomatal pores on their foliage and concurrent with photosynthesis.
