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. Alternate between sporophyte and gametophyte in the plant life cycle






2. Large compound formed from combinations of many monomers






3. Photosynthesis and storage






4. Lengthen roots and stem - produce xylem and phloem - ground tissue - and epidermis






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






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






7. Makes dermal tissue for bark






8. Brings leaf water and nutrients - exports sugars






9. Root hairs capture water and minerals and move them through (symplasticly) or between (apoplasticly) cells until the endodermis filters it into the vascular tissue






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






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






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






13. 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.

14. Rigid support - mostly found in bark. two types -- fibers and sclereids






15. Free energy in reactants stored in products (carbs)






16. General purpose cell. thin primary cell wall. most common






17. Part of leaf for photosynthesis






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






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






20. 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






21. Mycorrhizas and the bubble shaped guys






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






23. Increase population fitness in unstable environments






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






25. Change root structure entirely - make little bubble roots to help acquire nitrogen and phosphorous in exchange for sugars






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






27. CO2 - H2O - NADH - (ATP)






28. Synthesize proteins based on mRNA code






29. 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






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






31. Addition of H2O to break apart polymer






32. ***lets them be sexual?






33. Provides flexible support - like in celery






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






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






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






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






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






39. 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






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






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






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






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






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






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






48. Sorting and shipping of molecules






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






50. Attached directly by the base
