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. Removal of H2O to link monomer and polymers






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






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






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






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






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






7. Part of leaf for photosynthesis






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






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






10. Produces secondary vascular tissue






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






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






13. CO2 (exhale) + H20 + ATP (energy) ? CH20 (food) + 02 (air)






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






15. 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






16. Large compound formed from combinations of many monomers






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






18. Haploid - produces gametes through mitosis






19. Made of acetyl groups - structure energy and storage






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






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






22. Organic molecules (materials) - enzymes (workers) - DNA (blueprint)






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






24. Convert carbs into ATP






25. Diploid - produces spores through meiosis






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






27. Through cells






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






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






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






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






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






33. Mosses have no vascular tissue. Ferns reproduce with spores. Conifers reproduce with seeds. Flowering plants have flowers.






34. 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






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






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






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






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






39. ***lets them be sexual?






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






41. Makes dermal tissue for bark






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






43. Convert light energy to chemical energy






44. Produce vessels year round (ex. northern Arizona aspen)






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






46. Special pointy leaves made to protect the stem






47. Command center






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






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






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