Answers
1. These are male sex cells 1. These are female sex cells
2. produced in testis 2. produced in ovary
1.Ovum is large compared with sperm. Ovum (egg) contains the cytoplasm, mitochondria and half of the DNA for the new cell. The sperm contains the half of the DNA. Both halves from ovum and sperm will join and form the new diploid cell ( the embryo).
2.Ovum is formed and released cyclically. In regular 28 days menstrual cycle, the ovulation will occur in the 14th day of the cycle. There are two ovaries in female. So one side ovary will ovulate alternative cycles.
3.The sperm production is continuous. The sperm production and maturity takes about 70 -72 days. which is longer compared with ovum production.
4.The sperm is produced by the testis. Sperm production needs less than the body temperature. So the testis are kept in the scrotal bags which hangs out from the body. The core temperature of the testis is about 2 degree less than the body temperature.
5.The sperm is motile. It has a tail to swim. The active motility helps him to swim in the female reproductive tract and reaches the fallopian tube, there it meets the egg usually.
6.The life span of the sperm in the female genital tract is 72 hours. But ovum has a little shorter lifespan. Ovum will survive for 48 hours from the ovulation.
7.During ovulation only one ovum (usually) is produced in human. But in an ejaculation millions of sperm will be there in a ml of semen.
