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. Division and distribution of the cell's DNA to its two daughter cells such that each cell receives a complete copy of the original genome






2. Common passageway for both the reproductive and exretory systems






3. Produced when each meiotic division -rapidly degenerate






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






5. Sperm production -occurs in the seminiferous tubules






6. 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






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






8. 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






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






10. Part of embry that are seed leaves






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






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






13. Specialized sex cells






14. A means of reproduction






15. Surrounded by two layers of cells






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






17. Muscular chamber which is the site of fetal development






18. 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






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






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






21. 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






22. 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






23. Egg






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






25. Have two cotyledons that absorb the endosperm






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






27. 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






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






29. Homologous pairs (tetrads) align at the equatorial plane - and each pair attaches to a separate spindle fiber by its kinetochore






30. Flowering plants consisting of a few cells that exist for a very short time






31. Undergoes disjunction






32. AKA sperm production -occurs in the seminiferous tubules






33. 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






34. 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






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






36. 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






37. Part of embryo that grows and feeds the embryo






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






39. Union of gametes






40. Sporophyte generation is the dominant - familiar form






41. 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






42. Uncoiled DNA






43. Outer layer of oocyte cell membrane






44. 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






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






46. Cell division that follows karyokinesis






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






48. 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






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






50. Cut piece of stem can develop new roots in water or moist gorund - which can be used to accelerate root formation -layering: stems of certain plants - will take root when bent to the gorund and covered with soil -stem of one plant (scion) can be atta
