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 is a reactant in the photochemical reactions of photosynthesis?






2. Vascular and seed bearing






3. 'Alleles' are best described as...






4. Under what conditions would a plant utilize fermentation to obtain energy?






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






6. What type of RNA has a codon?






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






8. What causes diffusion of gases to occur?






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






10. What is a final product of aerobic respiration?






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






12. How does DNA replication take place?






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






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






15. What type of RNA has a codon?






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






17. 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.






18. What is NOT a function of the vacuole?






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






20. What are beneficial products made from bacteria?






21. 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






22. Have a nucleus - and a cell membrane






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






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






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






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






27. What type of RNA has an anticodon?






28. What is a final product of glycolysis?






29. How do bacteria reproduce?






30. Cladifils- modified stems that look like leaves - all parts are photosynthetic

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






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






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






34. During which phase of mitosis does the nuclear envelope disappear?






35. 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.






36. What contains the most potential energy?






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






38. 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






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






40. Have a nucleus - and a cell membrane






41. How do bacteria reproduce?






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






43. Three generations of gymnosperms






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






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






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






47. What hormone functions in stomatal closure and can be used to induce dormancy in cultivated plants?






48. 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.






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






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