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.
Detailed Description of the Experiment. Leaf stomata are the principal means of gas exchange in vascular plants. Stomata are small pores, typically on the undersides of leaves, that are opened or closed under the control of a pair of banana-shaped cells called guard cells (see figure above). When open, stomata allow CO2 to enter the leaf for synthesis of glucose, and also allow for water, H2O, and free oxygen, O2, to escape.
