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. Located on scrotum -site for testosterone






2. Muscular chamber which is the site of fetal development






3. (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






4. AKA stolon -woody - underground stems -can develop new upright stems






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






6. Central region where - after replication - the chromosomes consist of two identical sister chromatids held together in interphase






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






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






9. Haploid gametophyte gneration produces gametes by mitosis -gametophytes reproduce sexually - whereas the sporophyte gneration reproduces asexually






10. 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






11. 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






12. Nuclear division and followed by cell division






13. Formed due to cortical reaction -hard layer that surrounds the ovum cell membrane and prevents multiple fertilizations -Followed by the fusion of sperm nucleus and form a diploid zygote






14. Union of the egg and sperm nuclei to form a zygote with a diploid number of chromosomes






15. A means of reproduction






16. Consists almost entirely of the nucleus - which contains the paternal genome






17. 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






18. 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






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






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






21. Bulbs - tubers - runners - rhizomes






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






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






24. Mass of cells formed when the zygote divides






25. 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






26. 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






27. Have both functional male and female gonads






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






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






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






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






32. 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






33. Diploid cells that undergo meiosis to produce four haploid sperm of equal size






34. Menstrual flow






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






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






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






38. Releases spores form the undersides of its leaves that develop into small heart-shaped gametophytes






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






40. Part of embryo that grows and feeds the embryo






41. (In Anaphase I) homologous pairs separate and are pulled to opposite poles of the cell -accounts for a fundamental Mendelian Law -each chromosome of paternal origin separates (or disjoins) from its homologue of maternal origin - and either chromosome






42. Plant cells lack centrioles -spindle apparatus is synthesized by mcrotubule organizing centers that are not visible -cytokinesis in animal cells proceeds through production of a cleavage furrow -Plant cells are rigid and can't form cleavage furrows -






43. External pouch that maintains the testes' temperature at 2C-4C lower than body tmperature - a condition essential for sperm survival






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






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






46. Result when a single zygote splits into two embryos






47. Secretes estrogen and progesterone






48. Part of embry that are seed leaves






49. Triggered by acrosomal reaction causing calcium ions to be released into the cytoplasm






50. Nuclear membrane forms around each new nucleus -at this point - each chromosome still consists of sister chromatids joined at the centromere
