  1. 2. These cells provide nutrients to sperm cell & help reduce cytoplasm.
  2. 3. Sperm cells mature here
  3. 5. These types of cells form the body of the organism, are part of all different tissues, and generated by mitosis.
  4. 7. This cap is a like-organelle derived from Golgi, containing enzymes important to penetrate the oocyte.
  5. 8. This process generates four nonidentical haploid nuclei, whereas mitosis produces two identical diploid nuclei.
  6. 9. Covers the ovary and has several functions, including a role in ovulation by contributing to the follicular rupture, and transport and protection
  7. 11. Develops after ovulation and its main function is to produce hormones, primarily progesterone, to prepare the uterus for a possible pregnancy.
  8. 15. Sperm cells are released from these tubules
  9. 18. This type of reproduction introduces genetic diversity by mixing parental DNA.
  10. 19. The process by which spermatids mature into sperm cells.
Down
  1. 1. Entire structure in the ovary that contains and nurtures a developing oocyte. Two primary functions, protecting and maturing the oocyte and producing hormones.
  2. 4. These types of germ cells (PGCs) are the earliest precursor cells in an embryo that will develop into gametes (sperm or oocytes).
  3. 5. Transformation of primordial germ cells through mitosis, meiosis, and differentiation, resulting in the creation of haploid sperm capable of fertilizing an egg.
  4. 6. Immature, diploid cells that are the precursor to oocytes. Plural term of oogonium.
  5. 10. These cells release testosterone stimulating stem cells to differentiate into primary spermatocytes.
  6. 12. Process where a mature oocyte is released from an ovarian follicle in the ovary.
  7. 13. Primary oocytes remain in this stage of meiosis
  8. 14. Secondary oocytes remain in this stage of meiosis
  9. 16. Process of female gamete (egg cell) formation in the ovaries, involving cell division and maturation, beginning with a primordial germ cell and culminating in a mature ovum.
  10. 17. These types of cells are haploid and arise from germ line cells; combine during sexual reproduction to form a zygote.
