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






2. Special pointy leaves made to protect the stem






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






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






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






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






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






8. ***lets them be sexual?






9. Diploid - produces spores through meiosis






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






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






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






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






14. Attached directly by the base






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






16. Provides flexible support - like in celery






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






18. Brings leaf water and nutrients - exports sugars






19. 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






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






21. Glycolysis - krebs cycle - electron transport chain






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






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






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






25. CO2 - H2O - NADH - (ATP)






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






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






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






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






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






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






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






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






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






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






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






37. Produces secondary vascular tissue






38. Sorting and shipping of molecules






39. Photosynthesis and storage






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






41. Mycorrhizas and the bubble shaped guys






42. 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






43. A simple compound whose molecules can join together to form polymers






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






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






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






47. Part of leaf for photosynthesis






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






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






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