CNG is made by compressing natural gas (which is mainly composed of methane, CH4), to less than 1 percent of the volume it occupies at standard atmospheric pressure. It is stored and distributed in hard containers at a pressure of 20â25 MPa (2,900â3,600 psi), usually in cylindrical or spherical shapes.

A chloroplast is a type of plant cell organelle known as a plastid. Plastids assist in storing and harvesting needed substances for energy production. A chloroplast contains a green pigment called chlorophyll, which absorbs light energy for photosynthesis.Hence, the name chloroplast indicates that these structures are chlorophyll containing plastids.Like mitochondria, chloroplasts have their own DNA, are responsible for energy production, and reproduce independently from the rest of the cell through a division process similar to bacterial binary fission. chloroplast contains a green pigment called chlorophyll, which absorbs light energy for photosynthesis.
