Which graph shows most clearly what will happen to the rate of transpiration as humidity increases?
The diagram shows a potted plant and the same plant 24 hours later.
What causes the change in the appearance of the plant?
Water loss is greater than water uptake.
Water moves from the leaves to the stem.
Water uptake is equal to water loss.
Water uptake is greater than water loss.

A
B
C
D
In which order does water pass through the cells of a plant, as the water travels from the roots to a leaf?
mesophyll cells → root hair → root cortex → xylem
root cortex → root hair → xylem → mesophyll cells
root hair → mesophyll cells → root cortex → xylem
root hair → root cortex → xylem → mesophyll cells

What is a description of transpiration?
exchange of gases between the leaf and the atmosphere
loss of water vapour from the leaves and stems of a plan
movement of water from the roots to the leaves
