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 are the major groups of algae?






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






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






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






5. 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






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






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






8. 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






9. What type of RNA has an anticodon?






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

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






15. What contains the most potential energy?






16. What separates during meiosis-II






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






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






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






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






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






22. Transfer of DNA to RNA






23. Three generations of gymnosperms






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






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






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






27. What cell undergoes meiosis?






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






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






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


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






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






33. 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.






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






35. Vascular and seed bearing






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






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






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






39. What BEST describes plant hormones?






40. What is the role of endosperm?






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






42. During which phase of the cell cycle does DNA replication occur?






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