Question

Pea plants grow well in soils that are deficient in nitrogen.
Explain how root hair cells of pea plants absorb nitrate ions from soils with low nitrate concentrations

Answer 1

Answer:

Root hair cells in plants take in nitrate ions from the soil. Their concentration are often higher inside the root hair cell than in the soil, so the diffusion gradient is from the root hair à the soil. Despite this, the root hair cells still can take nitrate ions in, by active transport.
