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. Menstrual flow






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






3. 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






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






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






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






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






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






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






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






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






13. 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






14. 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






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






16. Diploid cells of spermatogonia






17. Have both functional male and female gonads






18. Produces monoploid spores that develop into pollen grains






19. Sporophyte generation is the dominant - familiar form






20. Centriole pairs are now at opposite poles of the cell






21. Result when a single zygote splits into two embryos






22. 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






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






24. 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






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






26. Muscular chamber which is the site of fetal development






27. (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






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






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






30. Specialized sex cells






31. Specialized organs where gametes are produced






32. Some species of plants have flowers that contain only stamens and other flowers that contain only pistils






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






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






35. Bulbs - tubers - runners - rhizomes






36. Replication of the nucleus followed by unequal cytokinesis -membrane pinches inward to forma new cell that is smaller in size but genetically identical to the parent cell






37. Sperm production -occurs in the seminiferous tubules






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






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






40. Split to form several bulbs






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






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






43. Located on scrotum -site for testosterone






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






45. (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






46. 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






47. A means of reproduction






48. Part of embryo that grows and feeds the embryo






49. Have one cotyledon






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