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. Large compound formed from combinations of many monomers






2. 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






3. Outer layer - barrier to animals and pathogens






4. Free energy plants get out of the reactant's potential energy






5. Made of acetyl groups - structure energy and storage






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






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






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






9. Increase population fitness in unstable environments






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






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






12. Convert light energy to chemical energy






13. Produces secondary vascular tissue






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






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






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






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






18. Makes dermal tissue for bark






19. Command center






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






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






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






23. CO2 - H2O - NADH - (ATP)






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






25. Special pointy leaves made to protect the stem






26. Between cells






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






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






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






30. Glycolysis - krebs cycle - electron transport chain






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






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






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






34. Convert carbs into ATP






35. Attached directly by the base






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






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






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






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






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






41. Brings leaf water and nutrients - exports sugars






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






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






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






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






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






47. Production of two spore types (gymnosperms and angiosperms)






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






49. Through cells






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