32. Leg-haemoglobin is an oxygen scavenger so how can it have an affinity for oxygen as in case of soyabean
Q.32. Roots of which plant contains a red pigment which have affinity for oxygen?
(a) Carrot
(b) Soybean
(c) Mustard
(d) Radish

Dear student

Please refer the solution below for the said query

The correct option is (b).

Oxygen scavengers are the molecules which can absorb or combine with oxygen. Leghaemoglobin is an iron containing protein with which oxygen binds so as to remove it from cytoplasm of infected plant cells. This ensures that nitrogenase enzyme required for nitrogen fixation functions efficiently. Leghaemoglobin is produced in the leguminous plants like soybeans. 

Hope this information clears your doubt about the topic.
