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. Alternate between sporophyte and gametophyte in the plant life cycle






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






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






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






5. Addition of H2O to break apart polymer






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






7. Makes dermal tissue for bark






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






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






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






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






12. 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






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






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






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






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






17. Removal of H2O to link monomer and polymers






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






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






20. Mycorrhizas and the bubble shaped guys






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






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






23. Made of acetyl groups - structure energy and storage






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






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






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






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






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






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






30. ***lets them be sexual?






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






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






33. 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






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






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






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






37. Change root structure entirely - make little bubble roots to help acquire nitrogen and phosphorous in exchange for sugars






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






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






40. Convert carbs into ATP






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






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






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






44. Proteins - lipids - carbohydrates - and nucleic acid






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






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






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






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






49. Part of leaf for photosynthesis






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