USE THIS PAGE TO EXPLORE AND ORGANIZE YOUR KNOWLEDGE ABOUT SPECIALIZED
CELLS USING A WEB.
What to Do
•
Answer the questions below in full sentences and complete the web organizer as
instructed.
1. What is meant by cell specialization?
Cell specialization refers to the idea that each cell has a specific job to do
within a multicellular organism.
2. Look at the web organizer below. Each spoke has a name of a different type of cell
found in human bodies. Underneath each cell name, draw what you think that type of
cell might look like - in other words, its structure. You can do this by thinking of the
specific function (its job) that each cell type must perform in the body. What structure or
shape might the cell have to help it best perform this function? I f you need assistance,
turn to pages 60-61 of SCIENCEPOWER™ 8.

3. How do you think the structure of each specialized cell might aid the cell's specific
function in the body? Explain for each cell below.
Nerve cell: A nerve cell is branched for receiving stimuli and long for sending
messages long distances within the body.
Muscle cell: A muscle cell is shaped for muscle contraction. It is able to pull the
ends together to shorten the muscle and therefore moving the body part.
Red blood cell: Red blood cells are smooth and round (streamlined) for easy
passage through the blood vessels. Thev also have high surface area.
Bone cell: Bone cells have many cross-fibres to give it strength and support.
Bone cells have strong connections between one another as well.
.
Skin cell: Skin cells are smooth and brick like, providing a smooth covering
around the body. They protect from the drying rays of the sun.

Now that you have predicted the shape and structure of different specialized
cells in the human body, it is time to see how close you were:
