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.
A chromosome (from ancient Greek: ÏÏÏÎ¼ÏÏÏÎ¼Î±, chromosoma, chroma means color, soma means body) is a DNA molecule with part or all of the genetic material (genome) of an organism. Chromosomes are normally visible under a light microscope only when the cell is undergoing the metaphase of cell division. Before this happens, every chromosome is copied once , and the copy is joined to the original by a centromere, resulting either in an X-shaped structure (pictured to the right) if the centromere is located in the middle of the chromosome or a two-arm structure if the centromere is located near one of the ends.
