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 calvin cycle where ATP and NADH are created






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






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






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






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






6. Photosynthesis and storage






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






8. Makes dermal tissue for bark






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






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






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






12. Indeterminate growth - assisted reproduction - protection (chemical deterence - spikes - internal resource transport)






13. Synthesize proteins based on mRNA code






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






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






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






17. Diploid - produces spores through meiosis






18. Mycorrhizas and the bubble shaped guys






19. CO2 - H2O - NADH - (ATP)






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






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






22. Brings leaf water and nutrients - exports sugars






23. Convert carbs into ATP






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






25. Produces secondary vascular tissue






26. 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






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






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






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






30. Made of acetyl groups - structure energy and storage






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






32. Special pointy leaves made to protect the stem






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






34. Haploid - produces gametes through mitosis






35. Increase population fitness in unstable environments






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






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






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






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






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






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






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






43. Removal of H2O to link monomer and polymers






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






45. Through cells






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






47. Outer layer - barrier to animals and pathogens






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






49. Large compound formed from combinations of many monomers






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