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. Bugs crawl into 'pitchers' - tiny hairs keep them from getting out - plant breaks down enzymes - and uses nitrogen. lives in places where nitrogen is limited.






2. Which part of the microscope would be adjusted to sharpen the image of a specimen at high magnification?






3. Southern US - prop roots hold it in place as water moves out - it can breathe under water.






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






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

18. Heating up bacteria until it is harmless and cannot function.






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






20. What is NOT a structure found on a typical flowering plant?






21. What is a product of the biochemical reactions of photosynthesis?






22. Epiphytes - valemine breaks down compost in roots
