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. What hormone is most important in the ripening of fruits?






2. What hormone stimulates cell division and may interfere with the function of auxin - leading to the development of 'witches-broom'?






3. What is a final product of aerobic respiration?






4. How are the vascular bundles of a dicot arranged in the stem?






5. What organelle contains DNA?






6. What type of RNA has an anticodon?






7. 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.






8. 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






9. Have a cell wall - no membrane - and no nucleus






10. Where in a plant is the water potential lowest?






11. What are harmful effects of bacteria?






12. The ocular lens of a microscope is 10x - and the objective lens is 4x. What is the total magnification of the microscope?






13. What is NOT a function of the vacuole?






14. Where in a dicot leaf does the majority of photosynthesis occur?






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






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






17. Three generations of gymnosperms






18. What BEST describes plant hormones?






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






20. What are beneficial products made from bacteria?






21. What is the main function of the roots of a corn plant?






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






23. Three generations of gymnosperms






24. How do bacteria reproduce?






25. In double fertilization - one sperm cell fertilized an egg cell - What does the other sperm cell fertilize?






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






27. Seeds are not protected by fruit and they do not have flowers - do not have shell around seeds - reproduce by releasing pollen into the air to make available to the ovule in the megaspores - causing fertilization






28. What are the major groups of algae?






29. How do bacteria reproduce?






30. Iodine can be used to test for what molecule - resulting in a blue-black color?






31. You can determine the age of a woody branch by counting these

34. What cell undergoes meiosis?






35. How are the vascular bundles of a dicot arranged in the stem?






36. What hormone is most important in the ripening of fruits?






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






38. An ecosystem with similar climatic conditions on earth - such as communities of plants - animals - and soil organisms






39. 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.






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






41. What is the role of endosperm?






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






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

45. What process involves the movement of water across a semi-permeable membrane?






46. What are beneficial products made from bacteria?






47. Composite organisms consisting of a symbiotic organism composed of a fungus with a photosynthetic partner - can be used as a natural fertilizer






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






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






50. Where in a dicot leaf does the majority of photosynthesis occur?
