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. Made of acetyl groups - structure energy and storage






2. Diploid - produces spores through meiosis






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






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






5. Produces secondary vascular tissue






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






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






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






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






10. Increase population fitness in unstable environments






11. 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






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






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






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






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






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






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






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






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






20. Provides flexible support - like in celery






21. Command center






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






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






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






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






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






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






28. Outer layer - barrier to animals and pathogens






29. Large compound formed from combinations of many monomers






30. Part of leaf for photosynthesis






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






32. Photosynthesis and storage






33. Through cells






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






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






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






37. Proteins - lipids - carbohydrates - and nucleic acid






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






39. 1. Prokaryotes are approximately the same size as their organelle counterparts. 2. Double membrane 3. Chloroplasts and mitochondria have their own unique circular DNA






40. Glycolysis - krebs cycle - electron transport chain






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






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






43. Brings leaf water and nutrients - exports sugars






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






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






46. Removal of H2O to link monomer and polymers






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






48. ***lets them be sexual?






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






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