<span>A mutually dependent relationship exists between chloroplast and mitochondria in the plant cell. Photosynthesis, which occur in the chloroplasts,generates the sugar and oxygen gas that are used in mitochondria for cellular respiration. It generates carbon-dioxide which in turn is used as a carbon source for the synthesis of sugars during photosynthesis.</span>
