Test your basic knowledge |

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. Production of two spore types (gymnosperms and angiosperms)






2. A chemical reaction involving the transfer of one or more electrons from one reactant to another; also called oxidation-reduction reaction.






3. Special leaves that act as arms that pull up or support the stem






4. Stick straight up and act like straws in swamp and mangrove plants






5. Organic molecules (materials) - enzymes (workers) - DNA (blueprint)






6. Produce vessels in spring and tracheids in winter (ex. oak tree)






7. The atmosphere is 21% oxygen - so that inherently means that over time plants have taken in more CO2 than they produce. this must be the case - otherwise we would all be dead.

8. Web of protein strands throughout the cell that allows organelles and molecules to move via motor proteins






9. Indeterminate growth - assisted reproduction - protection (chemical deterence - spikes - internal resource transport)






10. Cytoskeleton -- motor proteins carry molecules and organelles across microtubule tracks






11. Part of calvin cycle where five G3Ps are recycled - processed - and linked to form more materials for carbon fixation






12. Glycolysis - krebs cycle - electron transport chain






13. Mosses have no vascular tissue. Ferns reproduce with spores. Conifers reproduce with seeds. Flowering plants have flowers.






14. Part of calvin cycle where ATP and NADH are created






15. Attach themselves to other plants and suck nutrients out of the air (fog - humidity)






16. Waxy protection of leaf to protect from pathogens and let water run off it






17. Part of leaf that is loose for easy gas diffusion






18. Part of calvin cycle where ATP and NADH are turned into G3P (sugar)






19. Provide oxygen - food - medicine - fuel - shelter - paper products - beauty






20. Special pointy leaves made to protect the stem






21. Made of amino acids - structure (ex. cytoskeleton) - produce enzymes






22. Convert light energy to chemical energy






23. Produce vessels year round (ex. northern Arizona aspen)






24. Mycorrhizas and the bubble shaped guys






25. First step in releasing the energy of glucose - in which a molecule of glucose is broken into two molecules of pyruvic acid






26. Root apical meristem (quiescent center - or zone of cell division) - zone of elongation - zone of maturation






27. Penetrate root cortex into vascular tissue - aid in acquiring nitrogen and phosphorous in exchange for sugars






28. Comes in twos - sieve tubes (no nucleus) and companion cells (nourish sieve tubes) - transport sugars and nutrients






29. Provides flexible support - like in celery






30. Position reactants so they dont require as much activation energy






31. CO2 (air) + H20 (soil) + light energy (sun) ? CH20 (carbs) + 02 (oxygen)






32. Made of cellulose - structure and inter-cellular transportation of nutrients via plasmodesmata.






33. Synthesize proteins based on mRNA code






34. Ability crucial to plant structure and processing of energy - allows change to be made to help survival






35. Have underground stems that store starch (ex. potato)






36. Produces microgametophyte that stays with sporophyte plant (produces egg)






37. Practice of employing management strategies to allow healthy return of timber harvest. (ex. leave mature trees - plant seedlings)






38. Anchor the plant - collect water and nutrients from the ground






39. Part of leaf for photosynthesis






40. Gather and convert light energy - control CO2 and water loss






41. Inter-cellular links for long distance transportation of nutrients






42. Diploid - produces spores through meiosis






43. Photosynthesis and storage






44. Spore that gives rise to independent bisexual gametophyte that produces both egg and sperm (mosses and ferns)






45. Made of acetyl groups - structure energy and storage






46. Through cells






47. Outer layer - barrier to animals and pathogens






48. Free energy plants get out of the reactant's potential energy






49. A series of proteins in which the high-energy electrons from the Krebs cycle are used to convert ADP into ATP by redox reactions






50. A thin membrane around the cytoplasm of a cell - gatekeeper of the cell
