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






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






4. What is considered part of the protoplast?






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






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






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






8. Vascular and seed bearing






9. Traits that are desirable can be selected and bred for. process of selectively mating and breeding plants with particular traits.






10. Have a nucleus - and a cell membrane






11. What would be a way of keeping a short-day plant from blooming?






12. How does DNA replication take place?






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






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






15. What causes diffusion of gases to occur?






16. What are harmful effects of bacteria?






17. What cell undergoes meiosis?






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






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






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






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






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






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






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






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






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






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






28. What type of RNA has an anticodon?






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






30. What are the major groups of algae?






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






32. Transfer of DNA to RNA






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






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






35. How do bacteria reproduce?






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






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






38. 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






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






40. What BEST describes plant hormones?






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






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






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






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






45. How does DNA replication take place?






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






47. Have a nucleus - and a cell membrane






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






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






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