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.

29. Vascular and seed bearing






30. What BEST describes plant hormones?






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






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






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






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