When water TRANSPIRES from the stoma into the atmosphere, what phase is it in
Solid
Liquid
Gas
Which of the following helps to reduce the lose of water from a plant?
the arrangement of palisade mesophyll cells
the presence of xylem
the waxy layer of cuticle
the arrangement of spongy mesophyll cells
During day, stomata usually..
closed
opened
shrink
expand
Which of the following factors can affect the rate of transpiration?
the number of leaves
the number of flowers
the number of hydathodes
the amount of water in the soil
Why is the evaporation of water from leaves important?
It cools leaves and helps move water up the plant.
It makes the plant wilt
It helps the plant to respire
this stomata will cause...
reduce of water
increase of water
plant wilting
plant watered
Which of the following indicates the pathway of water through a plant?
root hair cell --> xylem --> Mesophyll --> substomatal space --> stomata
substomatal space -- > stomata --> root hair cell --> xylem --> Mesophyll
xylem --> stomata --> root hair cell --> Mesophyll --> Substomatal space
Select all of the environmental factors that would increase transpiration.
Choose more than 1
Increased humidity
Increased wind speed
Increased temperature
Decreased surface area
The direction of the wind
More root hairs will lead to
Less transpiration
More transpiration
Closure of stomata
More guttation
What is significance of transpiration
Creates suction force
Helps in distribution of water and nutrients
Cooling effect for plants
All of the above
Adaptations in plant to reduce transpiration are -
No of stomata
Thickness of cuticle
Loss of leaves
All of the above
By this process ..........
The water vapor will be lost
The leaf will be clear by the end of the day
substances will be deposited by the end of the day
Stoma will open
This experiment proves that ......
Transpiration helps in the water ascent
Transporting of water through xylem
Transpiration occurs by plants
Guttation occurs by plants
