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. CO2 - H2O - NADH - (ATP)






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






3. Cytoskeleton -- motor proteins carry molecules and organelles across microtubule tracks






4. Provides flexible support - like in celery






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






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






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






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






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






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






11. Removal of H2O to link monomer and polymers






12. Have underground stems that store starch (ex. potato)






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






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






15. Attached directly by the base






16. Brings leaf water and nutrients - exports sugars






17. Convert light energy to chemical energy






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






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






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






21. Outer layer - barrier to animals and pathogens






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






23. ***lets them be sexual?






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






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






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






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






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






29. Proteins - lipids - carbohydrates - and nucleic acid






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






31. 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






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






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






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






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






36. Between cells






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






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






39. Photosynthesis and storage






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






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






42. Produces secondary vascular tissue






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






44. 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






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






46. 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.

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






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






49. Synthesize proteins based on mRNA code






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