Different cells have different functions and their structure is different. Identify the cell illustrated on page 139, panel D. a) b) c) d) bone blood nerve muscle 8. Different cells have different functions and their structure is different. Identify the cell illustrated on page 139, panel C. a) b) c) d) bone blood nerve muscle Short Answer: Like instruments in an orchestra, different cells have different appearances and perform different jobs. They are said to be “specialized” – for particular tasks. Your muscle cells are shaped to move parts of your body and skin cells are built to protect your body from the sun and other things. 1. Fill out the chart below with the description of each specialized cells job and draw an approximate picture of what the cell looks like. Use pg. 139 to help you. The first function is done for you. Cell Nerve Blood Bone Skin Muscle Function These cells send electrical signals between the brain and other body parts through long, finger like fibers (strings) that reach from one cell to the next. Picture 2.
