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.

7. Differences in type and location of human-managed ecosystems - quantity and quality of available drinking water and air may also be affected by rising levels of atmospheric carbon dioxide






8. How many sperm cells does each pollen grain typically carry?






9. What are homologous chromosomes?

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






17. What organelle was observable in the onion epidermis stained with iodine?






18. Lives in desert - leaves have waxy cuticle - succulent - holds onto water

22. What is the role of endosperm?






23. What are the major groups of algae?






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