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. Part of leaf that is loose for easy gas diffusion






2. Diploid - produces spores through meiosis






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






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






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






6. 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






7. Sorting and shipping of molecules






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






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






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






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






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






13. Between cells






14. Free energy in reactants stored in products (carbs)






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






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






17. Makes dermal tissue for bark






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






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






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






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






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






23. Mycorrhizas and the bubble shaped guys






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






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






26. 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






27. Special pointy leaves made to protect the stem






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






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






30. Through cells






31. Outer layer - barrier to animals and pathogens






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






33. Made of acetyl groups - structure energy and storage






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






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






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






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. Convert carbs into ATP






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






40. Glycolysis - krebs cycle - electron transport chain






41. Command center






42. Synthesize proteins based on mRNA code






43. Haploid - produces gametes through mitosis






44. Proteins - lipids - carbohydrates - and nucleic acid






45. Large compound formed from combinations of many monomers






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






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






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






49. More effective in stable environments - focus on fast growth without competition






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