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






2. 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






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






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






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






6. Undergoes disjunction






7. Mass of cells formed when the zygote divides






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






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






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






11. 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






12. 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






13. 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






14. 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 -






15. Part of embry that are seed leaves






16. Contains elongated cell with head - tail - neck - and body






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. Produces monoploid spores that develop into pollen grains






19. Located on scrotum -site for testosterone






20. 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






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






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






23. 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






24. 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






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






26. The production of female gametes - occurs in the ovaries






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






28. Common passageway for both the reproductive and exretory systems






29. Outer layer of oocyte cell membrane






30. Regrowth of a lost or injured body part






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






32. Specialized sex cells






33. Inner layer of oocyte cell membrane






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






35. 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






36. Part of embryo that grows and feeds the embryo






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






38. 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






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






40. 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






41. Large cell containing most of the cytoplasm - RNA - organelles - and nutrients needed by a developing embryo






42. Sperm production -occurs in the seminiferous tubules






43. 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






44. Nuclear division and followed by cell division






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






46. Split to form several bulbs






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






48. Surrounded by two layers of cells






49. Stems running above and along the gorund - extending form the main stem -can produce new roots and upright stems






50. After ovulation - LH induces the ruptured follicle to develop into the corpus luteum
