Plant and animal cells are similar in their overall function as they must provide structure to tissues and carry out metabolic processes. Some of the organelles they use to do this are however different. Plant cells have a rigid cell wall, a structure that is absent in animal cells. The animal cell only has a more fluid cell membrane made of lipids. Plant and animal cells make energy using mitochondria but plant cells have an additional energy-making organelle, chloroplasts; these organelles are what makes plants green. Both plant and animal cells have a nucleus containing DNA, vacuoles that store waste, smooth and rough endoplasmic reticulum where membranes and proteins are produced, and the Golgi apparatus where secreted proteins are packaged and sent to the membrane. Here is a link to a YouTube video that nicely explains the differences between plant and animal cells, plant and animal cells.
