Worked Solution & Example Answer:Why do plant root hair cells use active transport to take in minerals? A - OCR Gateway - GCSE Biology - Question 12 - 2018 - Paper 1
Step 1
D. Minerals are present at very low concentrations in the soil.
Answer
Plant root hair cells utilize active transport to absorb minerals mainly because these minerals are often found in low concentrations in the soil compared to their concentration inside the root cells. Active transport allows the plant to move these essential nutrients against the concentration gradient, ensuring that they can intake the necessary minerals to support growth and metabolic functions.
