Transpiration
It is the losss of water as water vapour from the aerial parts/stems and leaves of the plants
The process of removal of water as water droplets from the aerial parts/leaf/stomata of a plant.
Exudation of sap from injured parts of a plant.
The loss of water in the from of water vapour from the surface of the leaf only.
Lenticels
They are present on the surface of leaves and stem.
They are present ont he surface of newly formed woody stem
They are present on the surface of older leaves and old woody stem
They are present on the surface of hard, old woody stemS
Water transported from stems to leaves through what?
xylem
phloem
stems
roots
Select all of the environmental factors that would increase transpiration.
Increased humidity
Increased wind speed
Increased temperature
Decreased surface area
Kidney shaped cells at the border of the stomata
Lenticels
Cuticle
Guard cells
Hydathodes
Adaptation to reduce transpiration
Broader leaves
absence of cuticle
More stomata
Narrow leaves
If plants don't store up water, how does water leave the plant?
The roots get rid of excess water.
Most plants DO store water.
It is released from the leaves by TRANSPIRATION.
Remember when you put the celery in the water? What happened to the water level by the next day?
The level dropped A LOT, because the celery sucked it up.
The level stayed the same, because the celery was dead.
The level dropped a little, because of evaporation.
Water molecules pull each other up the xylem due to ______________.
capillary action
root pressure
osmosis
active transport
Which statement correctly identifies the substance and direction it is transported in the xylem?
Water, only upwards
Glucose, only upwards
Water, up and down the plant
Glucose, up and down the plant
