ostia

guttation
"The openings on the stem through which transpiration occurs"

lenticels

protection against grazing
transpiration
fighting against infection
The rate of transpiration will be very less in a situation where
ground water is sufficient
wind is blowing
hot and dry environment
relative humidity is high

Adhesive and cohesive forces are
physical forces
chemical forces
electrical forces
magnetic forces
In which of the following plants there will be no transpiration?
Aquatic, submerged plants
Plants found in deserts
Aquatic plants with floating leaves
Plants growing in hilly regions
Stomata participate in
pollination
absorption
transportation
When water is lost in the form of droplets it is called
evaporation
If the rate of transpiration becomes more than the rate of photosynthesis, plants will
continue to live, but will not be able to store food
be killed instantly
grow more vigorously because more energy will be available
stop growing and gradually die of starvation
