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






2. Synthesize proteins based on mRNA code






3. 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






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






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






6. Command center






7. Produces bisexual spores - they become gametophytes w/ egg and sperm (study the picture)






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






9. Mycorrhizas and the bubble shaped guys






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






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






12. Flower to play the role of the gametophyte - producing two different spore types






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






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






15. Attached directly by the base






16. Made of acetyl groups - structure energy and storage






17. Make long thin stems called 'runners' that grow above ground and aid in asexual reproduction






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






19. Through cells






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






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






22. Convert light energy to chemical energy






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






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






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






26. Convert carbs into ATP






27. Consists of dead hollowed out cells - come in tracheids (long) or vessels (short) - move water in plant






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






29. Proteins - lipids - carbohydrates - and nucleic acid






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






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






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






33. When xylem is blocked by air bubbles as a result of gasses clotting together after freeze-thaw cycles or extreme water-tension






34. Photosynthesis and storage






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






36. CO2 - H2O - NADH - (ATP)






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






38. 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






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






40. Diploid - produces spores through meiosis






41. Cell walls of cellulose - photosynthesis - indeterminate growth - asexual and sexual reproduction






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






43. Made of monosaccharides - building blocks of life - sugars






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






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






46. Develop bordered pits to prevent spreading of bubbles - tracheids let water move laterally - refill at night - produce new xylem every spring






47. Glycolysis - krebs cycle - electron transport chain






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






49. Brings leaf water and nutrients - exports sugars






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