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.

10. What organelle was observable in the onion epidermis stained with iodine?






11. What is considered part of the protoplast?






12. The part of an apple most often eaten by people is receptacle tissue - not ovary - making this what type of fruit?






13. What hormone functions in stomatal closure and can be used to induce dormancy in cultivated plants?

16. What is a final product of glycolysis?






17. What phenomena explains how a photon can strike any chlorophyll molecule in the antennal complex and still reach the reaction center?

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






20. Have a nucleus - and a cell membrane






21. 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
