Re: What is a ciliated epithelial cell and a palisade cell?

Ciliated epithelial cells have many stalk-like structures that poke through one surface of the cell (cilia). Epithelial cells are commonly arrayed in layers that are one cell thick. The "sides" of the cells stick together to form the sheet while the remaining two surfaces are exposed to either the environment on the top or apical surface, and the bottom or basolateral surface. The cilia usually project through the apical surface. Each cell has many cilia. Cells can coordinate the motions of the cilia to create a wave-like motion which moves things that might be sitting atop the epithelial layer. For instance, a ciliated epithelium lines part of your respiratory tract. The cilia help move mucus and any particles trapped by the mucus away from the lung tissue. You cough up small amounts of this mucus every day -- more if you're sick or smoke.

Palisade cells are found in plants, particularly in the leaves. Thes cells possess organelles called choloroplasts which enable them to carry out photosynthesis for the purposes of producing food and energy for the plant.
