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. Production of two spore types (gymnosperms and angiosperms)






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






3. CO2 - H2O - NADH - (ATP)






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






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






6. 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






7. Part of leaf for photosynthesis






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






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






10. Diploid - produces spores through meiosis






11. Photosynthesis and storage






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






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






14. Command center






15. Special pointy leaves made to protect the stem






16. 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.

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






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






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






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






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






22. Proteins - lipids - carbohydrates - and nucleic acid






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






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






25. Through cells






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






27. Made of acetyl groups - structure energy and storage






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






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






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






31. Increase population fitness in unstable environments






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






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






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






35. Attached directly by the base






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






37. Addition of H2O to break apart polymer






38. Outer layer - barrier to animals and pathogens






39. Mycorrhizas and the bubble shaped guys






40. Convert light energy to chemical energy






41. Provides flexible support - like in celery






42. 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






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






44. Large compound formed from combinations of many monomers






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






46. Brings leaf water and nutrients - exports sugars






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






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






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






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