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






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






3. Sorting and shipping of molecules






4. Between cells






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






6. ***lets them be sexual?






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






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






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






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






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






12. Photosynthesis and storage






13. Made of acetyl groups - structure energy and storage






14. Convert carbs into ATP






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






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






17. Special pointy leaves made to protect the stem






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






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






20. Command center






21. Glycolysis - krebs cycle - electron transport chain






22. Provide oxygen - food - medicine - fuel - shelter - paper products - beauty






23. Through cells






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






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






26. Diploid - produces spores through meiosis






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






28. Outer layer - barrier to animals and pathogens






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






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






31. Haploid - produces gametes through mitosis






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






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






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






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






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






37. 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






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






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






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






41. 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.


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






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






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






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






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






47. Convert light energy to chemical energy






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






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






50. Synthesize proteins based on mRNA code
