There are 2 million sperm cells are in each drop of semen. The correct option is A. Sperm cells are the cells of male reproductive cells.
<h3>What are sperm cells?</h3>
Sperm cells are the cells present in the testis of the male. They are the gametes, which are the male reproductive cells, help in reproduction. In humans, the sperm cells are motile and long, with a head and a tail like flagella.
There are 2 million sperm present in one drop of semen, so there will be more than a thousand million sperm in the semen. Semen is the white, substance secreted by the male organ. It is made up of water, mucus, and plasma. It is secreted during the process of reproduction that fertilizes the egg of the female.
Thus, the correct option is A. 2 million regarding the number of sperm cells in each drop of semen.

Answer:
Plant hormones are among the most important biochemicals affecting plant growth and yield production under different conditions, including stress. Plant hormones include auxin, abscisic acid, ethylene, gibberellins, cytokinins, salicylic acid, strigolactones, brassinosteroids, and nitrous (nitric) oxide. Plant functioning under stress is affected by plant hormones, which can help the plant to tolerate the environmental stresses. A wide range of actions have been illustrated for plant hormones. If it is possible to regulate the activities of plant hormones under stress, the production of tolerant plant species will be more likely. Soybean [Glycine max (Merr.) L.] growth and activities, including the process of nodulation and biological N fixation with the N fixing bacteria Bradyrhizobium japonicum, are also regulated by plant hormones. The important point about plant hormones is their interactions and cross talk, affecting their activity and efficiency in plants under different conditions, including environmental stresses. Some of the most important findings related to the behavior of the soybean and its symbiotic B. japonicum under environmental stresses as affected by plant hormones are presented.
