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. Made of monosaccharides - building blocks of life - sugars






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






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






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






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






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






7. Increase population fitness in unstable environments






8. Sorting and shipping of molecules






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






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






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






12. Part of leaf for photosynthesis






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






14. Waxy protection of leaf to protect from pathogens and let water run off it






15. Convert light energy to chemical energy






16. Outer layer - barrier to animals and pathogens






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






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






19. Synthesize proteins based on mRNA code






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






21. Removal of H2O to link monomer and polymers






22. Large compound formed from combinations of many monomers






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






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






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






26. 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






27. Between cells






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






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






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






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






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






33. Addition of H2O to break apart polymer






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






35. Convert carbs into ATP






36. ***lets them be sexual?






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






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






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






40. Haploid - produces gametes through mitosis






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






42. Glycolysis - krebs cycle - electron transport chain






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






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






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






46. Root hairs capture water and minerals and move them through (symplasticly) or between (apoplasticly) cells until the endodermis filters it into the vascular tissue






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






48. 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






49. Through cells






50. Cytoskeleton -- motor proteins carry molecules and organelles across microtubule tracks
