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. Between cells






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






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






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






6. CO2 - H2O - NADH - (ATP)






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






8. Large compound formed from combinations of many monomers






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






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






11. Glycolysis - krebs cycle - electron transport chain






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






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






14. Attached directly by the base






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






16. A thin membrane around the cytoplasm of a cell - gatekeeper of the cell






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






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






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






20. Addition of H2O to break apart polymer






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






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






23. Outer layer - barrier to animals and pathogens






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






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






26. A chemical reaction involving the transfer of one or more electrons from one reactant to another; also called oxidation-reduction reaction.






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






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






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






30. Brings leaf water and nutrients - exports sugars






31. Made of acetyl groups - structure energy and storage






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






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






34. Photosynthesis and storage






35. Synthesize proteins based on mRNA code






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






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






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






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






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






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






42. Diploid - produces spores through meiosis






43. Haploid - produces gametes through mitosis






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






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






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






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






48. 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






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






50. Convert carbs into ATP
