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 development of an unfertilized egg into an adult organism






2. Surrounded by two layers of cells






3. Sperm production -occurs in the seminiferous tubules






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






5. Meristems provide a source of cells that can develop into an adult plant -can occur naturally or through human intervention -advantagous because it introduces no genetic variation and is a rapid form of reproduction






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






7. Located on scrotum -site for testosterone






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. 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






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






11. 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






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






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






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






15. Outer layer of oocyte cell membrane






16. Ex: estrogens and progesterone -synthesized by ovaries






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






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






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






20. Undifferentiated tissues in plants






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






22. Split to form several bulbs






23. Specialized organs where gametes are produced






24. Triggered by acrosomal reaction causing calcium ions to be released into the cytoplasm






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






26. Have one cotyledon






27. Steroid hormones necessary for normal female maturation -stimulate the development of the female reproductive tract and contribute to the development of secondary sexual characteristics and sex drive -responsible for the thickening of the endometrium






28. (In Prophase I) chromatids of homologous chromosomes break at corresponding points and exchange equivalent pieces of DNA -occurs between homologous chromosomes and not between sister chromatids of the same chromosomes (the latter are identical - so c






29. Mass of cells formed when the zygote divides






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






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






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






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






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






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






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






37. Undergoes disjunction






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






39. Cell division that follows karyokinesis






40. Muscular chamber which is the site of fetal development






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






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






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






44. Uncoiled DNA






45. Produced when each meiotic division -rapidly degenerate






46. 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






47. 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






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






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






50. 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
