Organelles are found in Eukaryotic cells and are tiny structures inside cells that carry out different functions to insure that homeostasis is maintained. In animals, the centriole is present and is needed during mitotic division. It gives rise to the spindle. Plant cells contain chloroplasts with the pigment chlorophyll, among others. Chlorophyll can absorb the radiant energy from the sun and with the presence of carbon dioxide and water, photosynthesis can occur. After the steps of photolysis and carbon fixation, glucose is formed. Plants can use this glucose as a food and energy source, and they are producers or autotrophs. Another organelle found in plant cells but not in animal cells is the non-living cell wall. It is composed of cellulose, a polysaccharide. The cell wall provides support and a framework as well as protection to the plant cell. These are the organelles that differ between plant and animal cells.

plant cells make their energy differently than animal cells. Plant cells have chloroplasts, which utilize chlorophyll in order to convert sunlight and CO2 into sugars (photosynthesis).  Animal cells and plant cells have mitochondria that convert sugars into energy (ATP in the cell).  However animal cells do not have chloroplasts.
