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






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






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






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






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






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






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






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 is NOT a structure found on a typical flowering plant?






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






11. What organelle contains DNA?






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






13. Transferring of the information from the DNA into the language of the mRNA.






14. What contains the most potential energy?






15. What are the major groups of algae?






16. What BEST describes plant hormones?






17. Info. carrying molecule - single stranded






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






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






20. How do bacteria reproduce?






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






22. What are beneficial products made from bacteria?






23. Have a nucleus - and a cell membrane






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






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. Transfer of DNA to RNA






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






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






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






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






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






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






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






34. What type of RNA has a codon?






35. What causes diffusion of gases to occur?






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






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






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






39. 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






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






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






42. What are harmful effects of bacteria?






43. Epiphytes - valemine breaks down compost in roots






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






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






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






47. How does DNA replication take place?






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






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






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