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
From root hairs water and salts pass into epidermal cells _______ cells, endodermis and finally into xylem.
guard cells
cortical
stomata
phloem
When water is lost in the form of droplets it is called
evaporation
bleeding
guttation
transpiration
Strong attraction between water molecules is called
Adhesive
Ascent of sap
Cohesion
Osmosis
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
Stomata of a plant open due to
influx of hydrogen ions
influx of calcium ions
influx of potassium ions
efflux of potassium ions
Guard cells help in
protection against grazing
fighting against infection
