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. Synthesize proteins based on mRNA code






2. Produces secondary vascular tissue






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






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






5. CO2 - H2O - NADH - (ATP)






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






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






8. 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






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






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






11. Glycolysis - krebs cycle - electron transport chain






12. Provides flexible support - like in celery






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






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






15. Lengthen roots and stem - produce xylem and phloem - ground tissue - and epidermis






16. General purpose cell. thin primary cell wall. most common






17. ***lets them be sexual?






18. Haploid - produces gametes through mitosis






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






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






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






22. Mycorrhizas and the bubble shaped guys






23. Develop bordered pits to prevent spreading of bubbles - tracheids let water move laterally - refill at night - produce new xylem every spring






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






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






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






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






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






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






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






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






32. Penetrate root cortex into vascular tissue - aid in acquiring nitrogen and phosphorous in exchange for sugars






33. Makes dermal tissue for bark






34. Convert carbs into ATP






35. Between cells






36. Removal of H2O to link monomer and polymers






37. 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






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






39. Made of acetyl groups - structure energy and storage






40. Increase population fitness in unstable environments






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






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






43. Part of leaf for photosynthesis






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






45. Brings leaf water and nutrients - exports sugars






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






47. Sorting and shipping of molecules






48. Attached directly by the base






49. Command center






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