How do plants absorb nutrients from soil ? Explain in detail about nitrogen and other nutrients.
Answers
Answer:
Certain types of bacteria called rhizobium, are present in soil. They convert gaseous nitrogen into usable form and release it into the soil. Plants absorb these soluble forms of nitrogen along with water and other minerals through roots. ... After the fulfillment of all nutrients plants synthesize proteins and fats.
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.
Mass Flow: Nutrient movement to the roots via water is called mass flow. As the corn plant transpires water, it draws water from throughout the soil profile up through the root system. Mass flow accounts for nutrient uptake of mobile nutrients, such as nitrogen and sulfur.
