The alveolar epithelium comprises two main cell types: the alveolar type I and alveolar type II cell. The type I cell is a complex branched cell with multiple cytoplasmic plates that are greatly attenuated and relatively devoid of organelles; these plates represent the gas exchange surface in the alveolus.
Below are some names and descriptions of organelles commonly found in cells. There is also an interactive cell viewer and game that can be used to learn about the parts of animal and plant cells.
