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 product of the biochemical reactions of photosynthesis?






2. 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.

19. What are beneficial products made from bacteria?






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






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






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






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






24. Three generations of gymnosperms






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






26. 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?






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






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






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






30. 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






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






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






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






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






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






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






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






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






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






40. How do bacteria reproduce?






41. 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.






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






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






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






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






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






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






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