An apparatus used to measure the rate of transpiration
Garreau's potometer
Darwin's potometer
Ganong's potometer
The rate of transpiration in directly proportional to the
humidity
surface area
pressure
carbon dioxide content increase
Adaptation to reduce transpiration
Broader leaves
Stunted growth
More stomata
Narrow leaves
Kidney shaped cells at the border of the stomata
Lenticels
Cuticle
Guard cells
Hydathodes
The plant that does not exhibit guttation is
Strawberry
Nasturtium
Mango
Banana
The function of hydathode is to cause
transpiration
photosynthesis
guttation
bleeding
How will you identify the experimental leaf as dicot?
taproot system
two cotyledons
parallel venation
reticulate venation
The kind of transpiration that takes place from the surface of leaves is
guttation
lenticular
cuticular
stomatal
The plants transpire more in
high humid conditions
low temperature
reduced pressure
calm day
This is not a precaution in the use of the potometer
The twig may not remain alive for long
The potometer should be water tight
The twig should be cut under water
The twig should be cut obliquely
What happens to the movement of air bubble if apparatus is kept in front of a fan
Air bubble does not move
Air bubble moves very little
Air bubble does not change its position
Air bubble moves very fast
The rate of transpiration increases with
High atmospheric CO2 level
Low water content of leaf
Shedding of leaves
Dry air
