Instructions:
Answer 50 questions in 15 minutes.
If you are not ready to take this test, you can

.
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.

24. The production of female gametes - occurs in the ovaries
Sporophyte Generation
epicotyl
Secondary Oocyte

25. 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
External Fertilization
Menstruation
