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. How is algae different from 'true' plants?






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






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.

10. What tissue can be found in a root but not in a stem?






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






12. What type of RNA has a codon?






13. What BEST describes plant hormones?






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






15. What structure is MOST important in generating root pressure?






16. Transfer of DNA to RNA






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






18. Vascular and seed bearing






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






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






21. What are beneficial products made from bacteria?






22. What is a final product of glycolysis?






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






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






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






26. Composite organisms consisting of a symbiotic organism composed of a fungus with a photosynthetic partner - can be used as a natural fertilizer






27. 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?






28. What are harmful effects of bacteria?






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






30. What BEST describes plant hormones?






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






32. Composite organisms consisting of a symbiotic organism composed of a fungus with a photosynthetic partner - can be used as a natural fertilizer






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






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






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






36. What causes diffusion of gases to occur?






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






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






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






40. Lives in california - it is a lily - waxy - thin - sharp leaves to stop water loss - holds water for up to 2 years.






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






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






43. Three generations of gymnosperms






44. 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






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






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






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






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