   GLYOXYSOMES DEFINITION; ➤ PLANTS CONTAIN AN ORGANELLE, WHICH IN ADDITION TO GLYCOLIC ACID OXIDASE     AND CATALASE  ALSO POSSESS A NUMBER OF ENZYMES THAT ARE NOT FOUND IN     ANIMAL CELLS. THIS ORGANELLE CALLED GLYOXYSOMES. THEIR ABUNDANCE; ➤ THEY ARE ARE MOST ABUNDANT IN PLANT SEEDLINGS, WHICH RELY UPON STORED     FATTY ACIDS TO PROVIDE THEM WITH THE ENERGY AND MATERIAL TO BEGIN THE     FORMATION OF A NEW PLANT. CONVERSION OF FATTY ACID⟶CARBOHYDRATES ➤ ONE OF THE PRIMARY ACTIVITIES IN THESE GERMINATING SEEDLINGS IS THE     CONVERSION OF STORED FATTY ACIDS TO CARBOHYDRATES. THIS IS ACHIEVED     THROUGH A CYCLE, GLYOXYLATE CYCLE, THE ENZYMES OF WHICH ARE LOCATED     IN THE GLYOXYSOMES. FUNCTION OF GLYOXYSOMES IN PLANTS; ➤ IN PLANTS, PEROXISOMES PLAY IMPORTANT ROLE IN BOTH CATABOLIC AND     ANABOLIC PATHWAYS. IN SEEDS RICH IN LIPIDS SUCH AS CASTOR BEAN AND    SOYABEANS, GLYOXYSOMES ...
