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.

Hypocotyl
19. 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 -
Primary Spermatocytes
Plant vs. Animal cells
Mitosis
Centromere
20. Immature ova -all that a female will produce during her lifetime are already in her ovaries at birth

Monocots
Menstrual Cycle
22. Uncoiled DNA
Hermaphrodites
Chromatin
Four Parts of Interphase
Interphase (Meiosis)
23. 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
Flagellum
Meisosis vs. Mitosis
Cytokinesis
Sexual Reproduction Requires
24. AKA lateral meristem -located between the xylem and phloem
Oogenesis
Sexual Reproduction Requires

25. Egg
Urethra
Sexual Reproduction Requires
Tubers
Ovum
26. Lower - narrow end of the uterus -connects with the vaginal canal
Asexual Reproduction
Cervix
Monocots
Immature ovum
27. 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
Ovaries
Estrogens
Meristems
Menstruation
28. 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
Oogenesis
Primary Oocytes
Ovulation

Cytokinesis
Estrogens
Internal Fertilization
Stamen
32. (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
