Select the correct statement from those given below.
1 Legumes are incapable of fixing nitrogen
2 Legumes fix nitrogen through bacteria living in fruits
3 Legumes fix nitrogen only by bacteria present in root nodules
4 All legumes have stem nodules
Explanation:
Legumes can fix nitrogen with the help of bacteria (Rhizobium) present in root nodules. Rhizobium forms symbiotic relationship with leguminous root.

Which enzyme catalyses transamination reactions?
1 Nitrogenase
2 Deaminase
3 Transaminase
4 Aminase
Explanation:
Glutamic acid is the main amino acid from which the transfer of \(\mathrm{NH}_{2}\), the amino group takes place and other amino acids are formed through transamination. The enzyme transaminase catalyses all such reactions.

Which one of the following produces nitrogen fixing nodules on the roots of Alnus?
1 Frankia
2 Rhodospirillum
3 Beijernickia
4 Rhizobium
Explanation:
The microbe, Frankia, produces nitrogenfixing nodules on the roots of nonleguminous plants e.g., Alnus.

The color of central portion of nodule formed due to legume-bacteria association for nitrogen fixation is Red or Pink because of ____
1 Leg-haemoglobin
2 Cambium
3 Heterocysts
4 Bulliform cells.
Explanation:
Central portion of nodules are red or pink. This is due to the presence of leguminous haemoglobin or leg-haemoglobin.
