Question

Which of the following transfers oxygen from lungs to other tissues of a plant ?​

Answer 1

Explanation:

Haemoglobin is one of the best known and more completely characterized proteins in biochemistry. In mammals, its function is the bi-directional transport of oxygen from lungs to tissues and of carbon dioxide from tissues to lungs. Thus, haemoglobin travels in the circulatory system through veins and capillaries inside the erythrocytes in the blood stream. Haemoglobin was described in plants a long time ago in the legume root nodule, and its function was suggested to be associated with the oxygen supply to the symbiotic bacteroid. However, the question remains as to how plant haemoglobin can exert this function, being enclosed in the static plant cell system.
