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






2. Mycorrhizas and the bubble shaped guys






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






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






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






6. Proteins - lipids - carbohydrates - and nucleic acid






7. Photosynthesis and storage






8. Gather and convert light energy - control CO2 and water loss






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






10. Made of acetyl groups - structure energy and storage






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






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






13. Part of leaf for photosynthesis






14. Convert carbs into ATP






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






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






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






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






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






20. Addition of H2O to break apart polymer






21. Produce vessels year round (ex. northern Arizona aspen)






22. Attached directly by the base






23. Molecule manufacturing where ribosomes are - and then products are sent to the Golgi Apparatus






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






25. Makes dermal tissue for bark






26. Haploid - produces gametes through mitosis






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






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






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






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






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






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






33. Convert light energy to chemical energy






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






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






36. Between cells






37. Increase population fitness in unstable environments






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






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






40. CO2 - H2O - NADH - (ATP)






41. Special pointy leaves made to protect the stem






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






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






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






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






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






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






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






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






50. Outer layer - barrier to animals and pathogens
