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. 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






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






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






4. Produces secondary vascular tissue






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






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






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






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






9. Addition of H2O to break apart polymer






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






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






12. Attached directly by the base






13. Develop bordered pits to prevent spreading of bubbles - tracheids let water move laterally - refill at night - produce new xylem every spring






14. Between cells






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






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






17. Production of two spore types (gymnosperms and angiosperms)






18. Removal of H2O to link monomer and polymers






19. 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






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






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






22. Comes in twos - sieve tubes (no nucleus) and companion cells (nourish sieve tubes) - transport sugars and nutrients






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






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






25. Synthesize proteins based on mRNA code






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






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






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






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






30. Made of acetyl groups - structure energy and storage






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






32. Makes dermal tissue for bark






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






34. ***lets them be sexual?






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






36. Proteins - lipids - carbohydrates - and nucleic acid






37. Command center






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






39. Convert carbs into ATP






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






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






42. Diploid - produces spores through meiosis






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






44. Brings leaf water and nutrients - exports sugars






45. Provides flexible support - like in celery






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






47. Convert light energy to chemical energy






48. Penetrate root cortex into vascular tissue - aid in acquiring nitrogen and phosphorous in exchange for sugars






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






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