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.

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






18. What cell undergoes meiosis?






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






20. What organelle contains DNA?






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

24. What structure is MOST important in generating root pressure?






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






26. How does DNA replication take place?






27. What cellular processes generate short carbon chains or skeletons which plants use to assemble amino acids and lipids?






28. What tissue can be found in a root but not in a stem?






29. Individuals best adapted to their environment reproduce offspring. it requires variation - heritability - and selection.
