Water uptake：练习题

Which part of a plant provides the large surface area required for the efficient uptake of water and mineral ions from the soil?

A student observes the pathway of water through a dicotyledonous plant. Which row correctly identifies the order of tissues through which water passes as it moves from the soil into the leaf?

Identify the structure in a plant root that provides a large surface area for the uptake of water and mineral ions.

Explain how the large surface area of root hair cells facilitates the process of water uptake.

A student investigates the pathway of water in a plant using a stain. Describe how the results would appear in a cross-section of the stem and explain this observation.

A student investigated the pathway of water through a plant by placing a celery stalk into a beaker of water containing a red dye.
(a) Name the specific tissue that would be stained red as the water moves up the stalk.
(b) Outline the pathway taken by water as it moves from the root hair cells to the mesophyll cells of a leaf.
