Bacteria reproduce by various means. The most common form of reproduction in bacteria is binary fission, in which one mother bacterial cell divides to form two daughter bacterial cells. Since there is no fusion of gametes, it is asexual mode of reproduction.
In humans, reproduction is a complex process in which two different sexes are involved. Male produces sperm which is injected into the female reproductive system. The fusion of sperm and female egg takes place inside the body of the female. Hence, this is sexual form of reproduction.
