(organelle: organism). Photosynthesis occurs within the organelle called the chloroplast. Photosynthesis happens in the plant kingdom called for example a sun flower uses the process of photosynthesis to make food for itself.
At least some plant cells contain photosynthetic organelles (plastids) which enable them to make food for themselves. With sunlight, water, and carbon dioxide, the plastids make sugars, the basic molecules needed by the plant. Free oxygen (O 2) is produced as a by-product of photosynthesis.he leaf can be thought of as a food factory. Leaves of plants vary in shape and size, but they are always the plant organ best suited to capture solar energy. Once the food is made in the leaf, it is transported to the other parts of the plant such as stems and roots.
