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






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






3. Convert carbs into ATP






4. Provides flexible support - like in celery






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






6. Makes dermal tissue for bark






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






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






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






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






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






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






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






14. Made of acetyl groups - structure energy and storage






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






16. Brings leaf water and nutrients - exports sugars






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






18. Convert light energy to chemical energy






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






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






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






22. Large compound formed from combinations of many monomers






23. Part of leaf for photosynthesis






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






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






26. Glycolysis - krebs cycle - electron transport chain






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






28. Sorting and shipping of molecules






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






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






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






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






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






34. Mosses have no vascular tissue. Ferns reproduce with spores. Conifers reproduce with seeds. Flowering plants have flowers.






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






36. Command center






37. 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






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






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






40. Between cells






41. Removal of H2O to link monomer and polymers






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






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






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






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






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






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






48. Haploid - produces gametes through mitosis






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






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