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. 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






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






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






4. The production of female gametes - occurs in the ovaries






5. Sporophyte generation is the dominant - familiar form






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






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






8. Bulbs - tubers - runners - rhizomes






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






10. Sperm production -occurs in the seminiferous tubules






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






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






13. Have one cotyledon






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






15. A means of reproduction






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






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






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






19. Have both functional male and female gonads






20. 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






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






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






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






24. 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






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






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






27. Eggs






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






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






30. Specialized sex cells






31. Muscular chamber which is the site of fetal development






32. Located on scrotum -site for testosterone






33. 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






34. Common passageway for both the reproductive and exretory systems






35. Mass of cells formed when the zygote divides






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






37. 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






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






39. Menstrual flow






40. When a diploid sporophyte generation produces ahaploid (monoploid) spore by meiosis - spores divide by mitosis to produce the haploid - or gametophyte - generation






41. 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






42. 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 -






43. 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






44. 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






45. Undergoes disjunction






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






47. Secretes estrogen and progesterone






48. Female gonads that produce oocytes






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






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