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






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

7. Which commonly eaten food is an example of a stem?






8. Transfer of DNA to RNA






9. 3 part molecule with a sugar - phosphate group - and nitrogenous base - carries genes






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






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






12. What is the primary function of collenchyma cells?






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






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






15. 3 part molecule with a sugar - phosphate group - and nitrogenous base - carries genes






16. What is NOT a structure found on a typical flowering plant?






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






18. 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






19. Three generations of gymnosperms






20. Which class of organic macromolecule stores the greatest amount of potential energy?






21. How do bacteria reproduce?






22. Southern US - prop roots hold it in place as water moves out - it can breathe under water.






23. What is a final product of glycolysis?






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






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






26. Change in gene frequency in a gene population over time.

28. What organelle contains DNA?






29. What type of RNA has an anticodon?






30. Change in gene frequency in a gene population over time.






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






32. What causes diffusion of gases to occur?






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






34. What type of RNA has a codon?






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






36. 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.






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






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






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






40. What are the major groups of algae?






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






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






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






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






45. 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






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






47. What organelle contains DNA?






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






49. 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.






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