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. Epiphytes - valemine breaks down compost in roots






2. What are beneficial products made from bacteria?






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






4. 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.






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






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






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






8. 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






9. What is the role of endosperm?






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






11. 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?






12. What type of RNA has an anticodon?






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






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






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






16. Have a nucleus - and a cell membrane






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






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






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






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






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






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






23. A tissue in Which mitosis takes place - giving rise to the secondary xylem.






24. What type of RNA has an anticodon?






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






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






27. How do bacteria reproduce?






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






29. What is a final product of glycolysis?






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






31. Info. carrying molecule - single stranded






32. 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






33. What are homologous chromosomes?






34. What are the major groups of algae?






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






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






37. 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






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

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






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






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






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






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






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






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






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






47. What is a function of the epidermis?






48. What type of RNA has a codon?






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






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