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. Produces secondary vascular tissue






2. Proteins - lipids - carbohydrates - and nucleic acid






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






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






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






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






7. Makes dermal tissue for bark






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






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






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






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






12. Part of calvin cycle where five G3Ps are recycled - processed - and linked to form more materials for carbon fixation






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






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






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






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






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






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






19. Synthesize proteins based on mRNA code






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






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






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






23. Brings leaf water and nutrients - exports sugars






24. Diploid - produces spores through meiosis






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






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






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






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






29. Increase population fitness in unstable environments






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






31. Convert carbs into ATP






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






33. Glycolysis - krebs cycle - electron transport chain






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






35. Command center






36. Made of acetyl groups - structure energy and storage






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






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






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






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






41. Convert light energy to chemical energy






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






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






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






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






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






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






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






49. Attached directly by the base






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