Question

1.Write any four ways by which plants get nitrogen for protein synthesis?

Answer 1

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. Sometimes farmers add nitrogenous fertilizer to their field to fulfill the need of nitrogen.

Answer 2

Plants can get nitrogen to synthesise protein by-

1) They modify some parts of their body such as apex of leaf and change themselves to become insectivorous plants.

2) Leguminous plants like- pea plants,etc. have rhisobium bacteria in their root nodules which also provide them nitrogen.

3.A bacteria called Rhizobium take atmospheric nitrogen and convert into a soluble form

4. They also take the nitrogen from the fertilizers added in soil.
