All plants and animals, dead or alive, are composed of cells. Cells are the building blocks of nature. All animal cells have certain structures, called organelles that identify the cell as an animal cell. The same is true of plant cells. Even though plant and animal cells are different, they do have many similar cell structures (organelles). The following table identifies organelles, classifies them as either plant or animal or both, provides a description of the organelle and a study section. This study method is designed to help you remember the parts of a cell by relating them to your own body. The highlighted portion of the note indicates organelles that are visible using a light microscope.
