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. Glycolysis - krebs cycle - electron transport chain






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






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






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






5. Convert light energy to chemical energy






6. Part of leaf that is loose for easy gas diffusion






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






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






9. Diploid - produces spores through meiosis






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






11. Synthesize proteins based on mRNA code






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






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






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






15. Made of acetyl groups - structure energy and storage






16. 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






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






18. Addition of H2O to break apart polymer






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






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






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






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






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






24. 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






25. Sorting and shipping of molecules






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






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






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






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






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






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






32. ***lets them be sexual?






33. Part of leaf for photosynthesis






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






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






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






37. Waxy protection of leaf to protect from pathogens and let water run off it






38. Photosynthesis and storage






39. Makes dermal tissue for bark






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






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






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






43. 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.

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






45. Special pointy leaves made to protect the stem






46. Brings leaf water and nutrients - exports sugars






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






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






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






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