Nitrogen; stems
c.)
Nitrogen; roots

Answer 1

The answer is c.) Nitrogen; root

The atmosphere is the layer of gases that repairs the Earth. The atmosphere also fixes the other planets in the solar system. The composition of the gases that make up the atmosphere is Oxygen (O2), Carbon Dioxide (CO2), and Nitrogen (N2). Nitrogen is the most abundant gas found in the atmosphere and this gas has a function in plant growth. Nitrogen is one of the main nutrients in the soil which plays a very important role in stimulating growth and giving the leaves a green color

The process of absorption of nitrogen from the atmosphere is carried out by nitrogen fixation. For example Rhizobium which lives on plant roots. Bacteria capture atmospheric nitrogen and convert it into ammonia (NH3) which can be taken up by plants and used to make organic molecules.
