PCAT Biology Reproduction

Subjects : pcat, biology
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Found in the abdominal cavity - below the digestive system -consist of thousands of follicles






2. Caplike structure - derived from the Golgi apparatus - develops over the anterior half of the head -contains enzymes needed to penetrate the tough outer covering of the ovum






3. Multilayered sac of cells that contains - nourishes - and protects an immature ovum -produce estrogen






4. Produces two intermediate daughter cells with N chromosomes with sister chromatids






5. Immature ova -all that a female will produce during her lifetime are already in her ovaries at birth






6. Nuclear division and followed by cell division






7. Chromatin condenses into chromosomes - the spindle apparatus forms - and the nucleoli and nuclear membrane disappear






8. Practiced by terrestrial vertebrates and provides a direct route for sperm to reach the egg cell -increased chance for fertilization success and females produce fewer eggs






9. Inner layer of oocyte cell membrane






10. Released from the ovary into the abdominal cavity and drawn into the nearby oviduct






11. Produced in developing placenta if fertilization occurs - maintaining the corpus luteum and - thus - the supply of estrogen and progesterone that maintains the uterus - until the placenta takes over production of these hormones






12. Part of embry that are seed leaves






13. Meristems provide a source of cells that can develop into an adult plant -can occur naturally or through human intervention -advantagous because it introduces no genetic variation and is a rapid form of reproduction






14. (In Prophase I) process where homologous chromosomes (chromosomes that code for the same traits - one inherited form each parent) come together and intertwine






15. Chromosomes condense - and the centriole pairs (in animals) separate and move towards the opposite poles of the cell. the spindle apparatus forms between them - and the nuclear membrane dissolves - allowing the spindle fibers to interact with the chr






16. After ovulation - LH induces the ruptured follicle to develop into the corpus luteum






17. Flowering plants consisting of a few cells that exist for a very short time






18. Part of embryo that develops into the lower and root






19. Ex: estrogens and progesterone -synthesized by ovaries






20. Have one cotyledon






21. A tubelike structure formed by the sperm once in contact with the membrane -extends to the cell membrane and penetrates it - fusing the sperm cell membrane with that of the ovum -Sperm nucleus now enters the ovum's cytoplasm to complete Meiosis II






22. (In Prophase I) chromatids of homologous chromosomes break at corresponding points and exchange equivalent pieces of DNA -occurs between homologous chromosomes and not between sister chromatids of the same chromosomes (the latter are identical - so c






23. Very similar to mitosis - except that meiosis II is not preceded by chromosomal replication -chromosomes align at the equator - separate and move to opposite poles - and are surrounded by a reformed nuclear membrane -new cells have the haploid number






24. Uncoiled DNA






25. Undergoes disjunction






26. Regrowth of a lost or injured body part






27. Division and distribution of the cell's DNA to its two daughter cells such that each cell receives a complete copy of the original genome






28. Split to form several bulbs






29. The site of sperm deposition during intercourse and is also the passageway through which a baby is expelled during childbirth






30. Male gonads - produce sperm in the tightly coiled seminiferous tubules






31. Produced after meioisis from spermatids that undergo a series of changes -AKA mature sperm -specialized for transporting the sperm nucleus to the ovum -elongated cell with a head - neck - body - and tail






32. Muscular chamber which is the site of fetal development






33. Secretes estrogen and progesterone






34. Part of embryo that grows and feeds the embryo






35. Hormonal secretions of the ovaries - the hypothalamus - and the anterior pituitary play important roles in the female reproductive cycle -divided into the follicular phase - ovulation - the luteal phase - and menstruation






36. Stems running above and along the gorund - extending form the main stem -can produce new roots and upright stems






37. AKA ovanan or fallopian tube -opens into the upper end of the uterus






38. Thin and stalk like with a terminal sac called the anther






39. The process by which a cell doubles its organelles and cytoplasm - replicates its DNA - and then divides into two






40. Four haploid cells produced from the second meiotic division after secondary spermatocytes






41. Begins with the cessation of the menstrual flow from the previous cycle -FSH (Follicle Stimulating Hormone) from the anterior pituitary promotes the development of the follicle - which grows and begins secreting estrogen






42. 1) G1: Initiates interphase. is described as the active growth phase and can vary in length. the cell increases in size and synthesizes proteins. the length of the G1 phase determines the length of the entire cell cycle 2) S: the period of DNA synthe






43. Homologous pairs (tetrads) align at the equatorial plane - and each pair attaches to a separate spindle fiber by its kinetochore






44. Steroid hormones necessary for normal female maturation -stimulate the development of the female reproductive tract and contribute to the development of secondary sexual characteristics and sex drive -responsible for the thickening of the endometrium






45. Daughter cells of unequal size produced from one primary oocyte per month completes meiosis I -expelled from the follicle during ovulation






46. Sporophyte generation is the dominant - familiar form






47. Regulates secondary male sex characteristics including facial and pubic hair and voice changes






48. Egg






49. Simple form of asexual reproduction seen in prokaryotic organisms -DNA replicates and a new plasma membrane and cell wall grow inward along the midline of the cell - dividing it into two equally size cells with equal maounts of cytoplasm - each conta






50. When a diploid sporophyte generation produces ahaploid (monoploid) spore by meiosis - spores divide by mitosis to produce the haploid - or gametophyte - generation
