Germ cells in the ovary produce many _.
Correct answer: B. Oogonia
- A. Spermatogonia
- B. Oogonia
- C. Zygospores
- D. Eggs
Explanation
Germ cells in the ovary, specifically oogonia, undergo a process called oogenesis to produce eggs or ova. However, it's important to note that the number of eggs a female is born with is finite and decreases over time. Unlike males who continuously produce sperm throughout their reproductive life, females are typically born with a fixed number of immature eggs that gradually decrease through a process known as follicular atresia. During fetal development, oogonia undergo mitotic divisions to increase their numbers. However, by the time a female is born, most of the oogonia have already undergone mitotic divisions and transformed into primary oocytes. Each primary oocyte is surrounded by a layer of cells and is arrested in prophase I of meiosis.

About Reproduction
Human reproduction covers the male and female reproductive organs, gamete formation, fertilization, implantation and hormonal regulation. The menstrual cycle includes ovarian and uterine changes controlled by pituitary and ovarian hormones, while sexually transmitted diseases are studied through their causes, transmission, symptoms, prevention and effects on fertility.
