Ans: When we have to define cellular organization, it can be said that it is basically just the division of the different individual components that are found in the cells of several organisms. We all are familiar with the fact that different organisms tend to have different cell types. However, the one thing common in these organisms is the type of components that are included in those cells. Some of these components then group together to form the cellular organisation. There are several components in these levels such as the nucleus, cell walls, cell membrane, ribosomes, plastids, nucleic acids and much more.
