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






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






3. Between cells






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






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






6. Attached directly by the base






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






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






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






10. 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.

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






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






14. Command center






15. Through cells






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






17. Special pointy leaves made to protect the stem






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






19. 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






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






21. Provides flexible support - like in celery






22. Convert light energy to chemical energy






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






24. Increase population fitness in unstable environments






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






26. Brings leaf water and nutrients - exports sugars






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






28. Glycolysis - krebs cycle - electron transport chain






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






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






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






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






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






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






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






36. Mycorrhizas and the bubble shaped guys






37. 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






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






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






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






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






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






43. Outer layer - barrier to animals and pathogens






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






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






46. Addition of H2O to break apart polymer






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






48. Convert carbs into ATP






49. Part of leaf for photosynthesis






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