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 leaf for photosynthesis






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






3. Provides flexible support - like in celery






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






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






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






7. Glycolysis - krebs cycle - electron transport chain






8. Proteins - lipids - carbohydrates - and nucleic acid






9. Brings leaf water and nutrients - exports sugars






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






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






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






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






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






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






16. Photosynthesis and storage






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






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






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






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






21. Between cells






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. Large compound formed from combinations of many monomers






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






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






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






27. ***lets them be sexual?






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






29. Command center






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






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






32. Rigid support - mostly found in bark. two types -- fibers and sclereids






33. Increase population fitness in unstable environments






34. Special pointy leaves made to protect the stem






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






36. Diploid - produces spores through meiosis






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






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






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






40. Haploid - produces gametes through mitosis






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






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






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






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






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






46. Attached directly by the base






47. Synthesize proteins based on mRNA code






48. Outer layer - barrier to animals and pathogens






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






50. Makes dermal tissue for bark
