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. Inter-cellular links for long distance transportation of nutrients






2. CO2 - H2O - NADH - (ATP)






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






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






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






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






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






8. Between cells






9. Makes dermal tissue for bark






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






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






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






13. Attached directly by the base






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






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






16. Mycorrhizas and the bubble shaped guys






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






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






19. 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






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






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






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






23. Photosynthesis and storage






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






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






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






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






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






29. The atmosphere is 21% oxygen - so that inherently means that over time plants have taken in more CO2 than they produce. this must be the case - otherwise we would all be dead.

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






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






32. Produces secondary vascular tissue






33. Haploid - produces gametes through mitosis






34. Rigid support - mostly found in bark. two types -- fibers and sclereids






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






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






37. Special pointy leaves made to protect the stem






38. Synthesize proteins based on mRNA code






39. Made of acetyl groups - structure energy and storage






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






41. Removal of H2O to link monomer and polymers






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






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






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






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






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






47. Proteins - lipids - carbohydrates - and nucleic acid






48. Second stage of cellular respiration - in which pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions






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






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