-All signal transduction cascades are shut down immediately so as to prevent the cell from mounting a response.
-Cells are unable to respond quickly to hormones, and therefore signal transduction cascades always occur over a long time.
-Cells have to be able to function alone, because they are unable to work together in a coordinated fashion.
-Cells often have to respond very quickly to changes in their internal and external environments.

All eukaryotic cells have within them a variety of different structures called organelles. Organelles are small and function much like organs function in a large organism. Some organelles are responsible for gathering cell energy, others for controlling cell activities. Plant cells have different organelles than animal cells but also share many also. They all have a large variety of sizes and functions and make life as we know if possible. Click the links in the yellow boxes for more detailed information on each of the organelles.
