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






2. Found in the abdominal cavity - below the digestive system -consist of thousands of follicles






3. Common passageway for both the reproductive and exretory systems






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






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






6. Large cell containing most of the cytoplasm - RNA - organelles - and nutrients needed by a developing embryo






7. 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






8. 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






9. Undergoes disjunction






10. Occurs midway through the cycle -a mature ovarian follicle bursts and releases an ovum -caused by a surge in LH (Luteinizing Hormone) that is preceded - and in part caused - by a peak in estrogen levels






11. Secretes estrogen and progesterone






12. Eggs






13. Production of functional sex cells by adult organisms -fertilization forms a zygote -development of the zygote into another adult - completing the cycle






14. If the ovum isn't fertilized - the corpus luteum atrophies - the resulting drop in progesterone and estrogen levels causes the endometrium (with its superficial blood vessels) to slough off - giving rise to menses






15. Near the end of telophase - the cytoplasm divides into two daughter cells - each wit a complete nucleus and its own set of organelles -In animal cells - a cleavage furrow forms - and the cell membrane indents along the equator of the cell and finally






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






17. Two haploid cells yielded from meiotic division of primary spermatocytes






18. Comlex process involving the formation and fertilization of gametes and regulation of these processes by bot parents






19. 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






20. Mass of cells formed when the zygote divides






21. The production of female gametes - occurs in the ovaries






22. First barrier that the sperm must penetrate -enzymes secreted by the sperm aid in penetration of the corona radiata -arosome is responsible for penetrating the zona pellucida; it releases enzymes that digest this layer - thereby allowing the sperm to






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






24. Produces monoploid spores that develop into pollen grains






25. Plants exhibit alternation of generation in which a diploid generation is succeeded by a haploid generation -diploid saprophyte generation produces haploid spores - which develop into the haploid saprophyte generation






26. Specialized organs where gametes are produced






27. 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






28. Undifferentiated tissues in plants






29. Produced when one diploid primary female sex cell undergoes meiosis in the ovaries






30. AKA lateral meristem -located between the xylem and phloem






31. Split to form several bulbs






32. 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






33. (In Prophase I) each chromosome consists of two sister chromatids - each synaptic pair of homologous chromosomes containing four chromatids






34. Part of embryo that is the precursor of the upper stem and leaves






35. Muscular chamber which is the site of fetal development






36. Nuclear division and followed by cell division






37. 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






38. Centromeres split so that each chromatid has its own distinct centromere - thus allowing sister chromatids to separate. The sister chromatids are pulled toward the opposite poles of the cell by the shortening of the spindle fibers. Spindle fibers are






39. Spore formation - vegetative propagation - and Artificial Vegetative Propagation






40. Ex: estrogens and progesterone -synthesized by ovaries






41. 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






42. Result when a single zygote splits into two embryos






43. Surrounded by two layers of cells






44. Uncoiled DNA






45. Bulbs - tubers - runners - rhizomes






46. 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






47. Found in the tips of roots and stems where growth in length occurs






48. Diploid cells of spermatogonia






49. Method of growth - development - and replacement of worn-out cells






50. Cell undergoes a period of growth and replication of genetic material before the initiation of mitosis -cell spends at least 90% of life in interphase -each chromosome is replicated so that during division - a complete copy of the genome can be distr
