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. Organic compounds not directly involved in normal growth of organism. Facilitates reproduction and defense against predators.






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






3. Produces secondary vascular tissue






4. Attached directly by the base






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






6. Synthesize proteins based on mRNA code






7. Mycorrhizas and the bubble shaped guys






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






9. Stores water and waste and ultimately determines the shape of the cell






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






11. Xylem and phloem - used for transportation of water and sugars in plant






12. Reactions of photosynthesis in which energy from ATP and NADPH is used to build high-energy compounds such as sugars. 1)reduction - 2)carbon fixation - 3)regeneration






13. More effective in stable environments - focus on fast growth without competition






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






15. Special pointy leaves made to protect the stem






16. 1) taking wood from an ecosystem also takes nutrients 2) seedling establishment isn't that easy -- lots of competition and herbivory to overcome in building a new forest






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






18. The OEC splits water and transfers the electrons to the P680 or cholorphyll reaction center. In the meantime - the photosystem is absorbing light energy and funnels the energy into the p680 - from which - through a series of redox reactions - the kin






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






20. Biological fuel. captured and stored through photosynthesis - extracted by mitochondria






21. Production of two spore types (gymnosperms and angiosperms)






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






23. Large compound formed from combinations of many monomers






24. Convert light energy to chemical energy






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






26. Number of ATP molecules from 1 glucose in cellular respiration (total produced -- 38 - total yield -- 36)






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






28. Allows plants to combat sessileness and control growth and allocate resources effectively to best compete/survive in their environment via meristems






29. Outer layer - barrier to animals and pathogens






30. Between cells






31. Removal of H2O to link monomer and polymers






32. The part of the leaf for protection and gas exchange






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






34. Glycolysis - krebs cycle - electron transport chain






35. Brings leaf water and nutrients - exports sugars






36. Proteins - lipids - carbohydrates - and nucleic acid






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






38. Photosynthesis and storage






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






40. Made of acetyl groups - structure energy and storage






41. 1. Prokaryotes are approximately the same size as their organelle counterparts. 2. Double membrane 3. Chloroplasts and mitochondria have their own unique circular DNA






42. Position leaves for max photosynthesis - provide resource transportation and storage - escape herbivores






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






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






45. CO2 (exhale) + H20 + ATP (energy) ? CH20 (food) + 02 (air)






46. Second stage of cellular respiration - in which pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions






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






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






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






50. Fuel - paper - construction materials - furniture - latex - resins - syrup
