PPT-G AMETOGENESIS OOGENESIS

Dr Samer Alnussairi Objectives Oogenesis prenatal amp postnatal Ovulation In preparation for fertilization Germ cells undergo Gametogenesis include . 11.4.1. Germinal epithelium cells (spermatogonium). Sertoli cell. Developing spermatozoa. spermatids. Leydig cell. Each time a spermatogonium divides it may either undergo mitosis, to maintain the number of spermatogonia, or spermatogenesis.. Understanding:. Spermatogenesis and oogenesis both involve mitosis, cell growth, two divisions of meiosis and differentiation.. Processes in spermatogenesis and oogenesis result in different numbers of gametes with different amounts of cytoplasm. By: . Mary Abdel . Messih. AP Biology and Biology H Teacher. 9th Grade Mentor.
