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 contains the most potential energy?






2. How do bacteria reproduce?






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






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






5. An ecosystem with similar climatic conditions on earth - such as communities of plants - animals - and soil organisms






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






7. What type of RNA has an anticodon?






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 separates during meiosis-II






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






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






12. What contains the most potential energy?






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






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






15. What is NOT a function of the vacuole?






16. What type of fruit develops from a cluster of many simple flowers?






17. What is a final product of aerobic respiration?






18. 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






19. What is the primary function of collenchyma cells?






20. 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.






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






22. What cellular processes generate short carbon chains or skeletons which plants use to assemble amino acids and lipids?






23. What are harmful effects of bacteria?






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






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






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






27. Have a nucleus - and a cell membrane






28. Change in gene frequency in a gene population over time.






29. What type of RNA has an anticodon?






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






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






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






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






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






35. What is a final product of glycolysis?






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






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






38. What are the major groups of algae?






39. 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






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






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






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






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






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






45. Which substances pass through the open stomata of a leaf?






46. How does DNA replication take place?






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






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






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






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