Highly organized structures in cell are the cell organelles. There are a number of Organelles present inside the cells and they are aimed to provide different functions in the cells. These are highly organized structures because their functions are based on their structures. For example, ribosomes are involved in the formation and transportation of proteins therefore, they are organized in such a manner to facilitate this activity. Nucleus is another organelle, which controls the activities of a cell. Nucleolus are present inside the nucleus which are involved in synthesis of proteins. Mitochondria is an organelle which is involved in the formation of ATP. Moreover, some other organized structures are ribosomes, endoplasmic reticulum, Golgi apparatus, lysosome, chloroplast, cell membrane, cell wall and vacuoles.
