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. 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






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






3. Underground stems with bubs - like the eyes of potatoes - that can develop into adult plants






4. Sporophyte generation is the dominant - familiar form






5. Undifferentiated tissues in plants






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






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






8. 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






9. 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






10. AKA sperm production -occurs in the seminiferous tubules






11. Result when a single zygote splits into two embryos






12. Contains elongated cell with head - tail - neck - and body






13. Located on scrotum -site for testosterone






14. 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






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






16. The development of an unfertilized egg into an adult organism






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






18. 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






19. Similar to mitosis in that a cell duplicates its chromosomes before undergoing the process -whereas mitosis preserves the diploid number of the cell - meiosis produces the haploid (1N) number - having the number of chromosomes






20. Can be fertilized during the 12-24hr after ovulation -occurs in the lateral - widest portion of the fallopian tube -sperm must travel through the vaginal canal - cervix - uterus - and into the fallopian tubes to reach the ovum






21. Gametophyte is the dominant generation -smaller - short lived organism that depends on the gametophyte for energy and nutrients - sporophytes grow on top of the gametophytes and produce spores that develop into gametophytes






22. Causes the glands of the endometrium to mature and produce secretions that prepare it for the implantation of an embryo -essential for the maintenance of the endometrium






23. Lower - narrow end of the uterus -connects with the vaginal canal






24. 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






25. Pass from the testes through the vas deferens to the ejaculatory duct and then to the urethra






26. Regrowth of a lost or injured body part






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






28. 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






29. Uncoiled DNA






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






31. 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






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






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






34. 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






35. Differs from asexual reproduction in that there are two parents involved and the end result is a geneticaly unique offspring -fusion of two gametes






36. Tail of sperm -propels the sperm - whereas mitochondria in the neck and body provide energy the locomotion






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






38. The process by which gametes are produced -involves two divisions of primary sex cells resulting in four haploid cells called gametes






39. Expanding partition that grows outward from the interior of the cell until it reaches the cell membrane






40. Female gonads that produce oocytes






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






42. Cell division that follows karyokinesis






43. Secretes estrogen and progesterone






44. 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






45. Nuclear division and followed by cell division






46. The production of female gametes -occurs in the ovarian follicles






47. A means of reproduction






48. Produces monoploid spores that develop into pollen grains






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






50. Undergoes disjunction
