Peroxisomes are cell organelles that are found in both plant and animal cells. This cell organelle does a similar job as the mitochondria organelle. However, it only has a single-wall membrane which holds all it together.
The peroxisome organelle looks like the lysosome organelle under a microscope. There are many peroxisome organelles within a cell and they are responsible for many jobs. Their main job is to transform nutrients into energy!
What Does A Peroxisome Do?
Transforming these fatty acids into energy is a two-step process. Firstly, the peroxisome breaks down the fatty acid into a chemical known as hydrogen peroxide. Hydrogen peroxide is a toxic chemical to the cell so the peroxisome must perform its second step. The second step is to break down the hydrogen peroxide into water and oxygen which the cell uses for other jobs. In both of these steps, energy is created for the animal or plant to use.

Other Facts About Peroxisome
Peroxisomes are one of the cell organelles that grow all the time. When a peroxisome gets big enough, it will split into two smaller peroxisomes. Another interesting fact is that they got their weird name because they create hydrogen peroxide. This can be helpful in remembering what a peroxisome does.
Peroxisomes exist in many places within an organism to provide energy for different things. In seed cells in a plant, peroxisomes create energy for the cell to grow. In leaf cells, peroxisomes create energy to help with photosynthesis.
