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






2. Attached directly by the base






3. Outer layer - barrier to animals and pathogens






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






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






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






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






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






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






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






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






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






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






14. CO2 - H2O - NADH - (ATP)






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






16. Glycolysis - krebs cycle - electron transport chain






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






18. Synthesize proteins based on mRNA code






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






20. 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






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






22. 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.

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






24. Produces secondary vascular tissue






25. Addition of H2O to break apart polymer






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






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






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






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






30. Brings leaf water and nutrients - exports sugars






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






32. Between cells






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






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






35. Proteins - lipids - carbohydrates - and nucleic acid






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






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






38. Makes dermal tissue for bark






39. Mycorrhizas and the bubble shaped guys






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






41. Provides flexible support - like in celery






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






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






44. Diploid - produces spores through meiosis






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






46. 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






47. Convert light energy to chemical energy






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






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






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