Nutrient Uptake into the root and plant cells
Before both water and nutrients are incorporated into plants, both must first be absorbed by plant roots.
UPTAKE OF WATER AND NUTRIENTS BY ROOTS
Root hairs, along with the rest of the root surface, are the major sites o…Read More
Cation exchange between soil & plants
Cation exchange
The ‘soil cations’ essential for plant growth include ammonium, calcium, magnesium, and potassium. There are three additional ‘soil cations,’ which are not essential plant elements but affect soil pH. The a…Read More
