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.

23. 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
Meristems
Second Meiotic Division
Sporophyte
Meristem Cells
24. (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
