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. Union of gametes






2. The embryonic undifferentiated cells that growth in higher plants are restricted to -undergo active cell reproduction






3. Menstrual flow






4. 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






5. Outer layer of oocyte cell membrane






6. 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






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






8. 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






9. 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






10. Sperm production -occurs in the seminiferous tubules






11. Part of embry that are seed leaves






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






13. 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






14. 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






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






16. 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






17. 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






18. Produces monoploid spores that develop into pollen grains






19. Common passageway for both the reproductive and exretory systems






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






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






22. Bulbs - tubers - runners - rhizomes






23. Have two cotyledons that absorb the endosperm






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






25. 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






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






27. Regrowth of a lost or injured body part






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






29. Result when a single zygote splits into two embryos






30. Specialized organs where gametes are produced






31. If the ovum isn't fertilized - the corpus luteum atrophies - the resulting drop in progesterone and estrogen levels causes the endometrium (with its superficial blood vessels) to slough off - giving rise to menses






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






33. Nuclear membrane forms around each new nucleus -at this point - each chromosome still consists of sister chromatids joined at the centromere






34. Central region where - after replication - the chromosomes consist of two identical sister chromatids held together in interphase






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






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






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






38. 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






39. (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






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






41. Specialized sex cells






42. Cell division that follows karyokinesis






43. 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






44. Produced when each meiotic division -rapidly degenerate






45. Have both functional male and female gonads






46. Occurs midway through the cycle -a mature ovarian follicle bursts and releases an ovum -caused by a surge in LH (Luteinizing Hormone) that is preceded - and in part caused - by a peak in estrogen levels






47. Female gonads that produce oocytes






48. Undergoes disjunction






49. 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






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