Both glyoxysomes and peroxisomes are microbody structures. However, glyoxysomes are predominantly found in plants and filamentous fungi (mold) cells, while peroxisomes are characteristic to animal cell type. They also differ in their enzymatic composition, as glyoxysomes contain enzymes needed for glyoxylate cycle while peroxisomes may lack those enzymes. Peroxisomes in turn contain enzymes (such as catalase, peroxidase, etc.) for hydrogen peroxide degradation, absent in plant cells.
