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






2. Attached directly by the base






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






4. Special pointy leaves made to protect the stem






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






6. Made of acetyl groups - structure energy and storage






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






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






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






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






11. CO2 - H2O - NADH - (ATP)






12. Proteins - lipids - carbohydrates - and nucleic acid






13. Convert light energy to chemical energy






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






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






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






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






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






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






20. Through cells






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






22. 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






23. Between cells






24. Increase population fitness in unstable environments






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






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






27. Command center






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






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






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






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






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






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






34. Provides flexible support - like in celery






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






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






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. Brings leaf water and nutrients - exports sugars






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






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






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






42. Diploid - produces spores through meiosis






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






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






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






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






47. Part of leaf for photosynthesis






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






49. Addition of H2O to break apart polymer






50. Synthesize proteins based on mRNA code
