What is the effect of pH on surface tension?
For most liquids, an increase in pH results in decreased surface tension. This has been attributed to lower attraction force between molecules when pH rises.
How do roots hairs help the function of roots?
They increase the surface area of the roots, allowing more water to be gathered and absorbed by the plant.
Are roots adapted to take in water because they have a small surface area?
No.Plant roots have large surface area,roots have root hairs to increase the surface area so that large amounts of water can be absorbed easily.
How do the root hairs increase the surface area of the roots?
they do this because they get thinner and thinner and spread out.
How do root hairs aid in the function of roots?
They increase the surface area of the roots, allowing more water to be gathered and absorbed by the plant.
How are plant roots adapted to their functions?
