  1. Activities of Cells Quiz 5A

  2. Order Among Cells unicellular multicellular

  3. Unicellular the cells survive by themselves paramecium

  4. multicellular Multicellular organisms divide the functions they need to perform among their many different cells.

  5. multicellular colonial tissue

  6. Tissue group of cells that perform a particular function

  7. multicellular organ

  8. Organ groups of different kinds of tissues that work together to accomplish a particular function

  9. multicellular system

  10. Order among cells unicellular multicellular colonial tissue organ system

  11. division of labor the condition in which certain organs and tissues of multicellular organisms perform specialized functions that are not being performed by other tissues and organs

  12. turgor pressure water pressure inside a plant cells central vacuole; causes the stiffness of the plant cell

  13. turgor pressure Turgor pressure supports most leaves and flower parts and many small plants.

  14. turgor pressure the force behind the crispness of plants

  15. energy the ability to do work two forms of energy: kinetic energy: energy in motion potential energy: energy in storage

  16. Other forms? Not all energy is either kinetic or potential - example nuclear energy.

  17. Examples of kinetic energy • Light • Electricity • Sound • Running • Breathing • Heat

  18. Examples of potential energy • Battery • Ball on top of hill • Food

  19. 2 basic types of organisms, based on how they obtain their energy: • Producer Organisms • Consumer Organisms

  20. Producer Organisms an organism that manufactures its own food Also called autotroph

  21. Producer Organisms • Called producers • Examples: plants or algae • Receive energy in the kinetic form and then store it as potential energy in sugar • They do not eat food • They make their own food

  22. Consumer Organisms an organism that uses food manufactured by other organisms Also called heterotroph

  23. Consumer Organisms • called consumers • Examples: animals, protozoans, fungi, humans • Obtain the energy they need from the food they consume • can consume producers directly and indirectly

  24. Two Important Biological Process of Cells • Cellular Respiration • Photosynthesis

  25. Cellular Respiration Cellular respiration is not the same thing as breathing. Respiration sometimes means breathing (inhaling and exhaling). Cellular respiration is a process which cells use to release energy from certain molecules.
