Chloroplast is a double-membrane bound organelle. The space limited by the inner membrane is called stroma. A number of organised flattened membranous sacs called the thylakoids are present in the stroma, which contains the chlorophyll. Like chloroplasts, the mitochondria are also double-membrane bound, with the outer and the inner membrane. The inner membrane forms a number of infoldings called the cristae. Golgi bodies, contain many disc-shaped sacs called cisternae. These cisternae are stacked parallel to each other.
During interphase, nucleus is highly extended and has elaborate nucleoproteins fibres called chromatin. During cell division, chromatin condenses to form chromosomes.
