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






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






3. Common passageway for both the reproductive and exretory systems






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






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






6. 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






7. Nuclear division and followed by cell division






8. 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






9. Result when two ova are released in one ovarian cycle and are fertilized by two different sperm






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






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






12. The embryonic undifferentiated cells that growth in higher plants are restricted to -undergo active cell reproduction






13. Specialized cells with hard coverings that prevent loss of water






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






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






16. Eggs






17. 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






18. AKA sperm production -occurs in the seminiferous tubules






19. 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






20. As in mitosis - the parent cell's chromosomes are replicated in the 2N number of sister chromatids






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






22. 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






23. Outer layer of oocyte cell membrane






24. Have both functional male and female gonads






25. The male organ of the flower and consists of a thin - stalk-like filament






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






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






28. Production of offspring without fertilization -form new organisms by a single parent cell -offspring are genetic carbon copies of their parent cells -genetically identical to the parent cells (except mutations) -ex: fission - budding - regeneration -






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






30. 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






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






32. Menstrual flow






33. Specialized organs where gametes are produced






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






35. 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






36. A means of reproduction






37. (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






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






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






40. 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






41. 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






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






43. Have one cotyledon






44. Undifferentiated tissues in plants






45. 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






46. Surrounded by two layers of cells






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






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






49. Union of gametes






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