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. Produces monoploid spores that develop into pollen grains






2. 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






3. 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






4. Very similar to mitosis - except that meiosis II is not preceded by chromosomal replication -chromosomes align at the equator - separate and move to opposite poles - and are surrounded by a reformed nuclear membrane -new cells have the haploid number






5. 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






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






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






8. Specialized sex cells






9. 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






10. 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






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






12. 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 -






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






14. 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






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






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






17. Secretes estrogen and progesterone






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






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






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






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






22. Undifferentiated tissues in plants






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






24. Muscular chamber which is the site of fetal development






25. 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






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






27. Bulbs - tubers - runners - rhizomes






28. 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






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






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






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






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






33. 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






34. Part of embryo that grows and feeds the embryo






35. Outer layer of oocyte cell membrane






36. Regrowth of a lost or injured body part






37. 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






38. 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






39. (In Prophase I) process where homologous chromosomes (chromosomes that code for the same traits - one inherited form each parent) come together and intertwine






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






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






42. 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






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






44. Diploid cells of spermatogonia






45. Located on scrotum -site for testosterone






46. Reproductive structure of angiosperms






47. Egg






48. 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






49. Eggs






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