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. Inner layer of oocyte cell membrane






2. Bulbs - tubers - runners - rhizomes






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






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






5. Undifferentiated tissues in plants






6. Part of embryo that grows and feeds the embryo






7. Passes through the penis and opens to the outside at its tip






8. Female gonads that produce oocytes






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






10. 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






11. Nuclear division and followed by cell division






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






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






14. 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






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






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






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






18. Surrounded by two layers of cells






19. 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






20. Eggs






21. Four haploid cells produced from the second meiotic division after secondary spermatocytes






22. 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






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






24. 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






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






26. Undergoes disjunction






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






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






29. 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






30. AKA sperm production -occurs in the seminiferous tubules






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






32. 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






33. Union of gametes






34. Menstrual flow






35. Produced when each meiotic division -rapidly degenerate






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






37. Egg






38. Cell division that follows karyokinesis






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






40. 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






41. 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






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






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






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






45. 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






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






47. Have two cotyledons that absorb the endosperm






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






49. 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






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