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.

20. Info. carrying molecule - single stranded






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






22. Which tissue system occurs throughout the plant - is made up of parenchyma - collenchyma - and sclerenchyma cells - and functions in storage - structural support - and metabolism?






23. What is a reactant in the photochemical reactions of photosynthesis?






24. Transfer of DNA to RNA






25. What would be a way of keeping a short-day plant from blooming?






26. How is algae different from 'true' plants?






27. What is a reactant in the photochemical reactions of photosynthesis?
