Real Plant Transport Enrichment practice questions
Tiny thread-like structures on roots that increase the surface area for absorbing water are called:
Leaf stalks
Petals
Leaf hairs
Root hairs ✓
Root hairs are the fine, thread-like extensions on roots that greatly increase the surface area in contact with soil water.
Why do root hairs help a plant absorb water more effectively?
They store extra water inside the root for dry days.
They carry the water from the root up to the leaves.
They give the root a larger surface for taking in water. ✓
They push the root deeper into the soil where the water is.
A larger surface area in contact with soil water means more water can be absorbed at once - that's the job of root hairs.
Leaves have tiny openings that let excess water escape into the air as vapour. How does this help the plant?
It helps the leaves take in more sunlight
It helps the stem make food for the plant
It helps pull water up from the roots ✓
It helps the roots absorb minerals from the soil faster
As water evaporates from a leaf's openings, it helps pull more water up through the stem from the roots, similar to how sipping through a straw pulls liquid upward.
A gardener cuts a piece of stem with no roots from a plant and puts it in a jar of water. After a few weeks, it grows roots. Roots usually take in water for a plant. How did the piece of stem stay alive before it grew roots?
It did not need any water to stay alive
Its cut stem took in water from the jar ✓
Its leaves took in water from the air around it
It was still joined to the roots of its parent
A stem has tubes that carry water. The cut end of the stem can take in water from the jar, which keeps it alive until it grows roots.
