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.
Within the inner membrane is the stroma, a fluid matrix that contains all the enzymes neccessary for photosynthesis as well as the chloroplast genome, ribosomes, and RNA for self-replication. The stroma flows around a system of thylakoids: membraneous, flattened sacs. Thylakoid membranes are the site of photosynthesis.he presence of chlorophyll in chloroplasts gives plant cells their green color. Although they are found in the cells of all green plants, chloroplasts are most dense in the leaves, where they can absorb the maximum amount of light energy. A single plant cell may contain up to 50 chloroplasts.
