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






2. Part of embryo that grows and feeds the embryo






3. Undergoes disjunction






4. 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






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






6. Sperm production -occurs in the seminiferous tubules






7. 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 -






8. Specialized cells with hard coverings that prevent loss of water






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






10. Uncoiled DNA






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






12. 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






13. Eggs






14. Bulbs - tubers - runners - rhizomes






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






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






17. 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






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






19. 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






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






21. Surrounded by two layers of cells






22. 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






23. Differs from asexual reproduction in that there are two parents involved and the end result is a geneticaly unique offspring -fusion of two gametes






24. External pouch that maintains the testes' temperature at 2C-4C lower than body tmperature - a condition essential for sperm survival






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






26. 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






27. AKA sperm production -occurs in the seminiferous tubules






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






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






30. Muscular chamber which is the site of fetal development






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






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. 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






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






35. 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






36. Underground stems with bubs - like the eyes of potatoes - that can develop into adult plants






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






38. Secretes estrogen and progesterone






39. Diploid cells of spermatogonia






40. 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






41. Occurs in vertebrates that reproduce in water (fish and amphibians) -female lays eggs in water and male deposits sperm in the vicinity -lack of direct passage of sperm from male to female reduces chances of fertilization considerably






42. Have both functional male and female gonads






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






44. Comlex process involving the formation and fertilization of gametes and regulation of these processes by bot parents






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






46. (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






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






48. 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






49. Reproductive structure of angiosperms






50. The male organ of the flower and consists of a thin - stalk-like filament
