Plants absorb mineral ions from the soil to maintain healthy growth and carry out essential biological processes.
Dissolved mineral ions are absorbed by root hair cells and transported throughout the plant. Name the specific tissue that transports water and dissolved mineral ions from the roots up to the leaves.
A deficiency of nitrate ions (NO3−\text{NO}_3^-NO3−) in the soil results in plants showing signs of chlorosis (yellowing of leaves) and severely stunted growth. Explain how a deficiency of nitrate ions causes stunted growth in plants.
