The three required components are: Reactants: carbon dioxide and water'. Catalyst: chlorophyll. Energy Source: sunlight. When the reactants are acted upon in the chloroplast of a leaf, the energy from sunlight is stored as molecular bonds in hydrocarbon (carbohydrate) molecules, and free oxygen is released.he three factors for photosynthesis sunlight, carbon dioxide and water. This is the process where plants make their food. The process takes place in the leaves. In this proce â¦ ss, carbon dioxide in taken by the plants and in return, they release oxygen. 4 people found this useful.
Stroma can refer to: 1) The connective supportive framework of a biological cell, tissue, or organ. 2) The fluid filled area of a chloroplast outside of the thylakoid membranes wherein the light-independent reactions (Calvin Cycle and Carbon fixation) of photosynthesis take place.
Stroma Function. Photosynthesis, the food making process of plants, uses light energy in order to create sugar or starch from water (H 2 O) and carbon dioxide (CO 2).
