Botany Test

Subject : science
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.

19. During which phase of mitosis do the sister chromatids separate?






20. Under what circumstance would sexual reproduction be more successful than asexual reproduction?






21. NO vascular tissue - NO roots - have modified photosynthetic tissue to help it absorb carbon dioxide without losing too much water - can survive in variety of environments - seedless - and commonly seen as mosses - hornworts - and liverworts.

32. During which phase of the cell cycle does DNA replication occur?






33. Seeds are not protected by fruit and they do not have flowers - do not have shell around seeds - reproduce by releasing pollen into the air to make available to the ovule in the megaspores - causing fertilization






34. Don't have roots or leaves - and are not producers - do not photosynthesize - and have cell walls made out of chitlin.






35. Traits that are desirable can be selected and bred for. process of selectively mating and breeding plants with particular traits.
