Objectives: Explain why <strong>cells</strong> are small<br />
Now Lets Talk about Cell Size...<br />
Remember Elephant Sized Amoebas??<br />
Why do Cells have to be small?<br />
If a cell's volume gets to large, the<br />
cell's surface area will not be able to<br />
take in enough nutrients or get rid of<br />
enough wastes fast enough to keep<br />
the cell alive.<br />
Multicellular organisms can be more complex<br />
because <strong>cells</strong> are <strong>specialized</strong>! Specialization allows<br />
some <strong>cells</strong> to do only 1 job. Therefore, the<br />
organism is more efficient. Multicellular organisms<br />
are larger which means they have fewer predators,<br />
so they most likely live longer. In addition if a<br />
unicellular organism's cell dies, the organism dies.<br />
If a multicellular organism's cell dies it does not<br />
mean the death of the organism.
