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






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






3. Convert carbs into ATP






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






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






6. Glycolysis - krebs cycle - electron transport chain






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






8. 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






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






10. Part of leaf for photosynthesis






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






12. Convert light energy to chemical energy






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






14. Made of acetyl groups - structure energy and storage






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






16. Sorting and shipping of molecules






17. Addition of H2O to break apart polymer






18. Provides flexible support - like in celery






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






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






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






22. Molecule manufacturing where ribosomes are - and then products are sent to the Golgi Apparatus






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






24. Diploid - produces spores through meiosis






25. Command center






26. Haploid - produces gametes through mitosis






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






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






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






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






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






32. Increase population fitness in unstable environments






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






34. Increase width (girth) of stems and roots - has vascular cambium and cork cambium






35. 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






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






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






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






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






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






41. Between cells






42. Attached directly by the base






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






44. ***lets them be sexual?






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






46. 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






47. Alternate between sporophyte and gametophyte in the plant life cycle






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






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






50. Photosynthesis and storage
