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.
Grana, or singular 'granum,' are stacks of thylakoids within chloroplasts. The thylakoids contain numerous integral and peripheral membrane proteins as well as chemicals important to photosynthesis.One of these important molecules is called chlorophyll, a pigment or compound that absorbs a specific wavelength of energy from sunlight to use in photosynthesis.he thylakoids are surrounded by the stroma, or the inner liquid portion of the chloroplast. Both the stroma and the thylakoids contain important molecules for photosynthesis.
