The water absorbed by plants is mostly used in photosynthesis.
True
False
Transpiration occurs mainly through the leaf stomata.
True
False
Water vapours move out of the stomata in plants by osmosis.
True
False
Transpiration pull helps transport the sugars stored in the roots up to the leaves.
True
False
The higher the density of stomata in the leaves, the higher is the transpiration rate of the plant.
True
False
The upper epidermis of water lily has fewer stomata than the lower epidermis.
True
False
The graph shows the effect of environmental factor X on the transpiration rate of a plant.
What can environmental factor X probably be?
temperature
light intensity
relative humidity
air movement
The graph shows the effect of environmental factor X on the transpiration rate of a plant.
Fill in the blanks with suitable words to explain how environmental factor X affects the transpiration rate of the plant.
Effect:
The transpiration rate of the plant (i)______________ with an increase in the magnitude of environmental factor X.
Explanation:
A higher magnitude of environmental factor X (ii)______________ the concentration gradient of water vapour between the air spaces in the leaves and the surrounding air. Thus, water vapour will diffuse out of the leaves more (iii)______________.
(a) increases；(b) increases；(c) rapidly
(a) increases；(b) reduces；(c) rapidly
(a) decreases；(b) increases；(c) slowly
(a) decreases；(b) reduces；(c) slowly
