- <u>Organelles only in animal cell</u>- <em>Centrioles</em> are present in animal cells which help in movement through structures like <em>flagella and cilia.</em>
- <u>Organelles present in both plant and animal cells</u>- <em>Ribosomes, nucleus,mitochondria, golgi complex, cell vacuoles, lysosomes</em> are present in both plant and animal cells.
