Question

Lance set up an experiment to investigate how the root of maize plants absorb mineral salts from the soil and he discovered the following points:
- If the roots were given a poison the prevented respiration, the plant did not
absorb any minerals.
- If the roots were in waterlogged soil and, therefore lacked oxygen, the plants
did not absorb any minerals

1. What conclusion could Lance draw from his results about how the roots os the maize plants absorb minerals?

2. What name is the given to the process by which Lance's maize plants absorb the mineral salts from the soil?

3. How is the process you named in 2. beneficial to cells?

Answer 1

I cannot Say this I don't know

Answer 2

The absorption of minerals in the soil is very low.

They dissolve in water and move more or less the soil in solution.

Root hair cells are modified to absorb the water out of soil by osmosis – they have a outsized surface area, skinny walls and are close to the xylem cells used for transporting water up the plant.
