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






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






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






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






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






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






8. Removal of H2O to link monomer and polymers






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






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






11. Mycorrhizas and the bubble shaped guys






12. 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.

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






14. Brings leaf water and nutrients - exports sugars






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






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






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






18. Increase population fitness in unstable environments






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






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






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






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






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






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






25. Provides flexible support - like in celery






26. Convert carbs into ATP






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






28. 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






29. Proteins - lipids - carbohydrates - and nucleic acid






30. Synthesize proteins based on mRNA code






31. Diploid - produces spores through meiosis






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






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






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






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






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






37. Attached directly by the base






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






39. Part of leaf for photosynthesis






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






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






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






43. CO2 - H2O - NADH - (ATP)






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






45. ***lets them be sexual?






46. Makes dermal tissue for bark






47. Made of acetyl groups - structure energy and storage






48. Sorting and shipping of molecules






49. Photosynthesis and storage






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