Cell Differences Introduction Structural Differences in Distinct Classes of Cells Thus far we have been describing the structure and function of eukaryotic animal cells. As we have mentioned earlier, there are different classes of cells. In this short section, we will discuss the major cellular differences between prokaryotic and eukaryotic cells, and between animal and plant cells. The diversity among various cells is a result of the varying functions and complexity of those cells. Because plants convert sunlight into energy rather than obtaining energy by eating food the way we humans do, plant cells require additional structures that can perform this function. While most structures between animal and plant cells are the same, there are a couple of additional structures that perform specific functions in plant cells that are unnecessary in animal cells. In contrast to eukaryote cells, prokaryotic cells lack membrane-bound organelles. Such
