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. Where in a plant is the water potential lowest?






20. What pigment is responsible for plants sensing day length?






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






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






23. What are harmful effects of bacteria?






24. Where in the chloroplast do protons accumulate - resulting in an electrochemical gradient which drives ATP-synthase?

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






48. What process would be used by a plant to move potassium ions across a membrane AGAINST a concentration gradient?






49. 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






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