Specialized Cells
Our bodies are composed of single cells that work together to make up tissues, which then work
together to make up organs, which work together to make up organ systems, which finally come
together to make up an organism. We are multicellular eukaryotic organisms. This means we are made
of more than one cell, and that all of the cells that make us up have a nucleus. However, not all the cells
that make up an organism are identical. Cells vary greatly in size, shape and structure, depending on
what function they have to perform for the organism.
Directions: You will make your way to 7 stations. At each station there is a different cell type. You will
explain how the structure of each of the different cell types makes that cell good at it s particular
function in the organism.
