Many bacteria have long, hair-like structures called **flagella** projecting from the cell wall. These are used for **motility**.<br /><br />2. The DNA of eukaryotes is organized into chromosomes and associated with proteins called **histones**.<br /><br />3. Eukaryotic ribosomes may be found associated with the **endoplasmic reticulum** or free in the cytoplasm.<br /><br />4. The Golgi apparatus **modifies, sorts, and packages** newly synthesized substances.<br /><br />5. **ria** are the site of energy generation in eukaryotic cells. In prokaryotic cells, some of these reactions take place at the **cell membrane**.<br /><br />6. The structure of flagella is more complex than that of **prokaryotes**, comprising an arrangement of **microtubules** made of **tubulin**.
