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






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






3. Addition of H2O to break apart polymer






4. Diploid - produces spores through meiosis






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






6. Haploid - produces gametes through mitosis






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






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






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






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






11. Part of leaf for photosynthesis






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






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






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






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






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






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






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






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






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






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






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






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






24. Sorting and shipping of molecules






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






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






27. 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






28. Large compound formed from combinations of many monomers






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






30. Provides flexible support - like in celery






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






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






33. Mycorrhizas and the bubble shaped guys






34. Produces secondary vascular tissue






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






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






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






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






39. Removal of H2O to link monomer and polymers






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






41. Comes in twos - sieve tubes (no nucleus) and companion cells (nourish sieve tubes) - transport sugars and nutrients






42. Made of cellulose - structure and inter-cellular transportation of nutrients via plasmodesmata.






43. Convert carbs into ATP






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






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






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






47. Between cells






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






49. Glycolysis - krebs cycle - electron transport chain






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