Talk about glyoxysomes.

Special form of peroxisomes involved in glyoxylatic cycle enzymes, other enzymes such as krebs cycle ones are also found, abundant in plant seeds usually rich in stored lipids. Germinating seedlings rely on lipids as a energy source since photosynthesis is no yet ready. They have to convert fatty acids into carbohydrates necessary for metabolism and ATP production in mitochondria as well as cell wall construction.
