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






2. Removal of H2O to link monomer and polymers






3. Command center






4. Outer layer - barrier to animals and pathogens






5. Provides flexible support - like in celery






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






7. Made of acetyl groups - structure energy and storage






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






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






10. Diploid - produces spores through meiosis






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






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






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






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






15. 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






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






17. Part of leaf for photosynthesis






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






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






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






21. Free energy plants get out of the reactant's potential energy






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






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






24. CO2 - H2O - NADH - (ATP)






25. Addition of H2O to break apart polymer






26. Large compound formed from combinations of many monomers






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






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






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






30. Synthesize proteins based on mRNA code






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






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






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






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






35. Attached directly by the base






36. Convert carbs into ATP






37. Brings leaf water and nutrients - exports sugars






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






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






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






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






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






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






44. Photosynthesis and storage






45. Mycorrhizas and the bubble shaped guys






46. Sorting and shipping of molecules






47. Special pointy leaves made to protect the stem






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






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






50. Proteins - lipids - carbohydrates - and nucleic acid
