- Watch this series of videos (http://openstaxcollege.org/l/oocyte) to look at the movement of the oocyte through the ovary. The cilia in the uterine tube promote movement of the oocyte. What would likely occur if the cilia wereparalyzed at the time of ovulation?(a) Compare the amount of cytoplasm and number of organelles in ova to that in sperm. (b) Explain why this difference is important to their function.During Sexual Reproduction what occurs when a sperm cell enters an egg cell?
- What is the role or function of mitosis and meiosis in formation of the sperm and egg cell?Name the plasma membrane outside the mature ovum.Describe the events that must occur in order for sperm to penetrate an egg. What prevents more than one sperm from entering? In the case of twins, how many sperm entered the egg? Why must a man have millions of sperm in a semen sample to be considered fertile? If only one sperm were present in the semen and that sperm managed to find its way to the egg, could it fertilize the egg?
