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 the main function of the roots of a corn plant?






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






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






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






5. 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






6. How does DNA replication take place?






7. Have a nucleus - and a cell membrane






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






9. What organelle contains DNA?






10. 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.






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






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






13. What is considered part of the protoplast?






14. What cell undergoes meiosis?






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






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






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






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






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






20. What is a final product of glycolysis?






21. 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.






22. 'Alleles' are best described as...






23. What phenomena explains how a photon can strike any chlorophyll molecule in the antennal complex and still reach the reaction center?






24. Vascular and seed bearing






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






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






27. What cell undergoes meiosis?






28. What phenomena explains how a photon can strike any chlorophyll molecule in the antennal complex and still reach the reaction center?






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






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






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






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






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






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






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






36. What is the role of endosperm?






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






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






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






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






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






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






43. How does DNA replication take place?






44. What is NOT a function of the vacuole?






45. What type of RNA has a codon?






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






47. Cladifils- modified stems that look like leaves - all parts are photosynthetic


48. What are the major groups of algae?






49. What contains the most potential energy?






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