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 is NOT a product of the krebs cycle?






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






4. What is a final product of glycolysis?






5. What is a final product of aerobic respiration?






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






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






8. What BEST describes plant hormones?






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






10. What is the role of endosperm?






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






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






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






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






15. How does DNA replication take place?






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






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






18. What are harmful effects of bacteria?






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

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






22. What contains the most potential energy?






23. 'Alleles' are best described as...






24. 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.






25. In what portion of a root might you find 'root hairs'?






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






27. Have a nucleus - and a cell membrane






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






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






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






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






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






33. What causes diffusion of gases to occur?






34. Where in a dicot leaf does the majority of photosynthesis occur?






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






36. What separates during meiosis-II






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






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






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






40. Info. carrying molecule - single stranded






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






42. What separates during meiosis-II






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






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






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






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