Peroxisomes:

The small cell like unit where eukaryotic cell is of mosaic in nature is Peroxisomes. It can either grow or divide on its own. It is surrounded by a membrane, similar to all other cell organelles. They are rich in enzyme which is synthesized metabolically. Under certain condition they bring out enzymes for oxidative metabolism. In addition to this, they have digestive enzymes. Each organelles of cell induce different metabolic process by individual Peroxisomes. For instance, Peroxisomes which are present inside the liver has the capability of detoxifying the ethanol.

Structure of Peroxisomes: Single membrane which is just 0.5 micron in diameter which encloses cell membrane. Nearly 70 to 100 Peroxisomes can be found in the cell.

Functions: They are responsible for catabolic and anabolic pathways in plants. Lipid Peroxisomes oxidize long chain fatty acids by beta oxidation metabolism. However short chain fatty acids are oxidized in mitochondria. They are also capable of generating and detoxifying free radicals. They play active role in immunity by destroying foreign pathogens especially by producing hydrogen radicals from hydrogen peroxide. Immune system is recognized by preserving the part of foreign protein.

Glyoxisomes: These are a kind of micro bodies. Peroxisomes that are found in plants are referred as Glyoxisomes. Especially, it is seen in abundant in germinating seeds which stores fats in its tissue and at times in filamentous fungi also. It comprises an enzyme which can convert one of the polysaccharide ultimately in to sugar.  Peroxisomes in seeds act as energy source by the oxidation of fatty acids to glucose.
