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






2. Produces megagametophyte that stays with sporophyte plant (produces egg)






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






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






5. Proteins - lipids - carbohydrates - and nucleic acid






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






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






8. CO2 - H2O - NADH - (ATP)






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






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






11. Produces secondary vascular tissue






12. Mycorrhizas and the bubble shaped guys






13. Haploid - produces gametes through mitosis






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






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






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






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






18. 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






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






20. Alternate between sporophyte and gametophyte in the plant life cycle






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






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






23. Addition of H2O to break apart polymer






24. Made of acetyl groups - structure energy and storage






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






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






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






28. Between cells






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






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






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






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






33. Attached directly by the base






34. Increase population fitness in unstable environments






35. Produce vessels in spring and tracheids in winter (ex. oak tree)






36. 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






37. Provides flexible support - like in celery






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






39. Made of monosaccharides - building blocks of life - sugars






40. 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.


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






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






43. 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






44. Through cells






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






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






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






48. Convert carbs into ATP






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






50. Glycolysis - krebs cycle - electron transport chain
