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. Removal of H2O to link monomer and polymers






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






3. Produces secondary vascular tissue






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






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






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






7. Diploid - produces spores through meiosis






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






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






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






11. Part of leaf for photosynthesis






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






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






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






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






16. Mycorrhizas and the bubble shaped guys






17. Through cells






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






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






20. CO2 - H2O - NADH - (ATP)






21. Sorting and shipping of molecules






22. Command center






23. Synthesize proteins based on mRNA code






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






25. Convert light energy to chemical energy






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






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






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






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






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






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






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






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






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






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






36. Increase population fitness in unstable environments






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






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






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






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






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






42. Haploid - produces gametes through mitosis






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






44. Brings leaf water and nutrients - exports sugars






45. Large compound formed from combinations of many monomers






46. Glycolysis - krebs cycle - electron transport chain






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






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






49. ***lets them be sexual?






50. 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
