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






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






3. Produced when each meiotic division -rapidly degenerate






4. Union of gametes






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






6. 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






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






8. 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






9. Replication of the nucleus followed by unequal cytokinesis -membrane pinches inward to forma new cell that is smaller in size but genetically identical to the parent cell






10. The process by which gametes are produced -involves two divisions of primary sex cells resulting in four haploid cells called gametes






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






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






13. 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






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






15. AKA stolon -woody - underground stems -can develop new upright stems






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






17. Found in the tips of roots and stems where growth in length occurs






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






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






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






21. Undifferentiated tissues in plants






22. 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






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






24. Sporophyte generation is the dominant - familiar form






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






26. Inner layer of oocyte cell membrane






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






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






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






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






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






32. Result when a single zygote splits into two embryos






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






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






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






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






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






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






39. Have two cotyledons that absorb the endosperm






40. Muscular chamber which is the site of fetal development






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






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






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






44. (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






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






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






47. Uncoiled DNA






48. 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 -






49. 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






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