Day 3Sec 7.3—Eukaryotic

Cell Structure

Plant Cells Compared with Animal CellsBoth plant and animal cells are eukaryotic cells, but the structures of both types of cells have major differences. Animal cells do not have a cell wall. Instead of a cell wall, the plasma membrane (usually called cell membrane when discussing animal cells) is the outer boundary of animal cells. Plant cells have both a cell wall and a plasma membrane. Animal tissues therefore require either external or internal support from some kind of skeleton, known as the cytoskeleton.  Centrioles are generally not found in plant cells, while they are found in animal cells. Animal cells do not have chloroplasts, but they are common in plant cells because plants make their own food through the process of photosynthesis. Both cell types have vacuoles, however, in animal cells vacuoles are very tiny, while in plant cells vacuoles are generally quite large. In many types of plant cells, particularly in species like conifers and flowering plants, there is an absence of flagellae and centrioles that are found in animal cells. There is another major difference between plant and animal cells. While the former turn carbon dioxide into sugar, it is the animal cells that break the sugar back down to carbon dioxide to make energy.
