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






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






3. Have both functional male and female gonads






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






5. Specialized sex cells






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






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






8. AKA sperm production -occurs in the seminiferous tubules






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






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






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






12. Located on scrotum -site for testosterone






13. Nuclear division and followed by cell division






14. 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






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






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






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






18. Undifferentiated tissues in plants






19. 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






20. Reproductive structure of angiosperms






21. 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






22. 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






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






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






25. The spindle apparatus disappears. A nuclear membrane forms around each set of newly formed chromosomes. Thus - each nucleus contains the same number of chromosomes (the diploid number 2n) as the original or parent nucleus. The chromosomes uncoil - re






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






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






28. Specialized organs where gametes are produced






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






30. Cell division that follows karyokinesis






31. Regulates secondary male sex characteristics including facial and pubic hair and voice changes






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






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






34. 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






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






36. A means of reproduction






37. 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






38. 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 -






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






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






41. Uncoiled DNA






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






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






44. 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 -






45. 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






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






47. Egg






48. Mass of cells formed when the zygote divides






49. Produced when each meiotic division -rapidly degenerate






50. Common passageway for both the reproductive and exretory systems
