Cell Structure

Cell Structure

Cell Structure. The “little organs” that perform important functions in the cell are Organelles. Cell Structure. There are two main parts (areas): The Nucleus controls the cells activities and contains DNA (genetic material ). Everything outside of the nucleus is the Cytoplasm.
