Question

root hair cells need a supply of sugars to provide energy. explain how root hair cells obtain a supply of sugars

Answer 1

Answer:

Photosynthesis in the leaves!

Explanation:

It is produced in the leaves by photosynthesis and is transported to the root hair cells.

Answer 2

The absorption of water by plants from the soil is done through osmosis. The plant absorbs mineral ions through active transport which is against the concentration gradient.

Explanation Of How Root Hair Cells Obtain A Supply Of Sugars

• Root hair cells are adapted for absorbing water and mineral ions as they have a large surface area for increasing the rate of absorption.

• Root hair also includes lots of mitochondria, which release energy from glucose (sugars) during the process of respiration for providing the energy which is required for active transport.

• Then the absorbed water is transported through the roots to the other parts of the plant where it is needed for different purposes like acting as a reactant for photosynthesis, for supporting leaves and shoots by keeping the cells rigid, by cooling the leaves through evaporation and for transporting dissolved minerals around the plant.
