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.
1. During which phase of mitosis does the nuclear envelope disappear?






2. In double fertilization - one sperm cell fertilized an egg cell - What does the other sperm cell fertilize?

4. What type of fruit develops from a cluster of many simple flowers?






5. How is algae different from 'true' plants?






6. What BEST describes plant hormones?






7. 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






8. Lives in dry - hot/cold - windy places - has fuzzy hairs to distance wind from the leaves

18. What are beneficial products made from bacteria?






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






20. Seedless - multicellular - and terrestrial - have a vascular system - reproduce by spreading spores that are found on the underside of mature leaves.






21. Which part of aerobic respiration results in the production of CO2?






22. What is the main function of the roots of a corn plant?
