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 part of a stem can a tree live without?






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






3. Which substances pass through the open stomata of a leaf?






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






5. Lives in dry - hot/cold - windy places - has fuzzy hairs to distance wind from the leaves






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






7. Seedless - multicellular - and terrestrial - have a vascular system - reproduce by spreading spores that are found on the underside of mature leaves.






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






9. Epiphytes - valemine breaks down compost in roots






10. During which phase of mitosis do the sister chromatids separate?






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






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. Which part of the microscope would be adjusted to sharpen the image of a specimen at high magnification?






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






15. What is a final product of glycolysis?






16. What organelle do guard cells contain that other epidermal cells lack?






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






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






19. Three generations of gymnosperms






20. What is NOT a product of the krebs cycle?






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






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






23. What is considered part of the protoplast?






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






25. Info. carrying molecule - single stranded






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

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






31. How does DNA replication take place?






32. What BEST describes plant hormones?






33. What pigment absorbs energy and can emit an electron in photosynthesis?






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






35. What is considered part of the protoplast?






36. Vascular and seed bearing






37. What causes diffusion of gases to occur?






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






39. A plant that carries two different versions of a gene for a single trait is...






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






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






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






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






44. Which substances pass through the open stomata of a leaf?






45. What are harmful effects of bacteria?






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






47. What are the major groups of algae?






48. 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.






49. What is NOT a function of the vacuole?






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