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






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






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






4. Mycorrhizas and the bubble shaped guys






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






6. Haploid - produces gametes through mitosis






7. Special pointy leaves made to protect the stem






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






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






10. Diploid - produces spores through meiosis






11. Addition of H2O to break apart polymer






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






13. Convert carbs into ATP






14. Synthesize proteins based on mRNA code






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






16. Brings leaf water and nutrients - exports sugars






17. Through cells






18. Attached directly by the base






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






20. Proteins - lipids - carbohydrates - and nucleic acid






21. Sorting and shipping of molecules






22. Xylem and phloem - used for transportation of water and sugars in plant






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






24. Produces secondary vascular tissue






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






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






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






28. Convert light energy to chemical energy






29. Part of leaf for photosynthesis






30. Removal of H2O to link monomer and polymers






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






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






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






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






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






36. Between cells






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






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






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






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






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






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






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






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






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






46. Made of acetyl groups - structure energy and storage






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






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






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






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