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 part of a stem can a tree live without?






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






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






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






5. What is a final product of glycolysis?






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






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






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






10. 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.






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






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






13. What are homologous chromosomes?






14. What organelle contains DNA?






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






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






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






18. What separates during meiosis-II






19. 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.






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






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






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






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






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






25. What is a function of the epidermis?






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






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






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


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






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






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






32. What is NOT a function of the vacuole?






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






34. 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.






35. What is the role of endosperm?






36. Info. carrying molecule - single stranded






37. What cell undergoes meiosis?






38. Epiphytes - valemine breaks down compost in roots






39. Vascular and seed bearing






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






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






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

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






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






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






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






48. 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






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






50. What is a reactant in the photochemical reactions of photosynthesis?
