Answer:
Three elements, carbon, oxygen and hydrogen, are essential to plant growth and are supplied by air and water.
Explanation:
Plants take up essential elements from the soil through their roots and from the air (mainly consisting of nitrogen and oxygen) through their leaves. Nutrient uptake in the soil is achieved by cation exchange, wherein root hairs pump hydrogen ions (H+) into the soil through proton pumps.
