Here's a coloring page that features sixteen different types of cells: prokaryotes, eukaryotes, protists, and cells from animals, plants, and the human body.
This packet includes a coloring page, directions, and a coloring guide page that includes information on which organelles the student can expect to find in each cell.
You might consider two related products. I have also created a "Collection Two" page identical in format to this but with different cells. In addition, I have a "Let's Cell-ebrate!" class poster activity that allows each student to learn much more about one specific type of cell, to color an annotated illustration of that cell, and to contribute it to a class cell quilt. All three of these products work very well together.
