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. Which tissue system occurs throughout the plant - is made up of parenchyma - collenchyma - and sclerenchyma cells - and functions in storage - structural support - and metabolism?






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






3. 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.






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






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






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






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






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






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






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






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






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






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






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






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






16. What contains the most potential energy?






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






18. Epiphytes - valemine breaks down compost in roots






19. What are the major groups of algae?






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






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






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






23. What plant tissue functions in conducting water from the roots to the leaves?






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






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






26. What causes diffusion of gases to occur?






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






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






29. What are beneficial products made from bacteria?






30. What is a final product of aerobic respiration?






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






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






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






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






35. What are adenine - guanine - thymine - cytosine?






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






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






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






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






40. Which part of aerobic respiration generates the most ATP?






41. What are harmful effects of bacteria?






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






43. 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.






44. What is the role of endosperm?






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






46. What is a final product of aerobic respiration?






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






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






49. 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






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