4. SpecializedcellsaredeterminedbyDNAandtheyarespecializedtodoaspecificjob.Whatisthespecialjobof‐‐ TypeofSpecializedCells SpecializedJob  Transporting oxygen from the lungs to all of the body tissues.

  Is capable of motility, and defends the body against infection and disease by ingesting foreign materials and cellular debris

 

Muscle cells are specialized for contraction. Muscles allow for motions such as walking, and they also facilitate bodily processes such as respiration and digestion.

  Designed to stimulate other cells in the body in order to communicate.

 

Support and protection of soft tissues, calcium and phosphate storage, and harboring of bone marrow. Is also where Red Blood Cells are created.

 Glucose + Oxygen

Water + Carbon Dioxide + Sunlight (energy)



 Glucose + Oxygen

6CO2 + 6H2O

 -> C6H12O6 + 602

 6. Compareandcontrastthetwotypesofcelltransport. ActiveTransport

Water + Carbon Dioxide + ATP (energy)

 C6H12O6 + 602

->

6H2O + 6CO2 + energy

PassiveTransport

  Does not require energy Requires energy input in order to move things across the cell membrane.  Movements of solutes down the concentration gradient. Movements of solutes against a concentration gradient. -Diffusion - Facilitated Diffusion - Osmosis  - Endocytosis - Exocytosis 

7. DescribehowthefollowingtypesofActiveTransportworks.  ActiveTransport Endocytosis Exocytosis   A cell releases a substance Howdoesitwork? Moves molecules in and out  Cell membranes eat/lingests of the cell using a protein pump food or liquids into the cell like hormones or wastes  in the cell membrane through the cell membrane.   Whatdoesitusetomovethings  Vesicle Vesicle Protein Pump acrossthecellmembrane? Whattypeofthingsdoesitmove acrossthecellmembrane?

   TypeofOsmosis Isotonic Solutionsw Hypertonic Soltution    Since water will move outside Whathappens Nothing because both sides are tothecell? the cell, the cell will shrink and balanced and the cell is normal  die. 

 Hypotonic Solution Since the water will move inside the cell, the cell will swell, or burst, and die....
