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






2. How does DNA replication take place?






3. During which phase of meiosis do daughter cells become haploid?






4. Enzymes are an example of what type of molecule?






5. What type of RNA has an anticodon?






6. What is NOT a function of the vacuole?






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. What part of a stem can a tree live without?






9. How does DNA replication take place?






10. 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






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






12. NO vascular tissue - NO roots - have modified photosynthetic tissue to help it absorb carbon dioxide without losing too much water - can survive in variety of environments - seedless - and commonly seen as mosses - hornworts - and liverworts.






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






14. If an ovule is fertilized - what will it develop into?






15. A gymnosperm - lives in the desert for up to 3000 years - only grows 2 leaves - 5 feet across - they receive 1 inch of lower of rainfall per year - roots can grow under the soil at least a mile.






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






17. What BEST describes plant hormones?






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






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






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






21. What best describes a dry fruit which opens at maturity?






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






23. What is the role of endosperm?






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






25. During which phase of the cell cycle does DNA replication occur?






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






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






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






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






30. What is a final product of glycolysis?






31. What pigment is responsible for plants sensing day length?






32. What is the function of the cortex in a root?






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






34. What causes diffusion of gases to occur?






35. Transferring of the information from the DNA into the language of the mRNA.






36. In what part of a flower is pollen produced?






37. What separates during meiosis-II






38. Transfer of DNA to RNA






39. What contains the most potential energy?






40. What BEST describes plant hormones?






41. A piece of potato tuber is placed in a concentrated sugar-water solution. what statement BEST describes why the piece of potato shrinks in size over time?






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






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






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






45. What is a final product of glycolysis?






46. In what portion of a root might you find 'root hairs'?






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






48. What best describes a dry fruit which opens at maturity?






49. Under what circumstance would sexual reproduction be more successful than asexual reproduction?






50. What type of fruit develops from a cluster of many simple flowers?
