* Centrioles: These are small, cylindrical structures involved in the formation of microtubules, which are important for cell division.
* Lysosomes: These are membrane-bound organelles that contain enzymes for breaking down waste products and cellular debris.
* Cilia and Flagella: These are hair-like projections that help with cell movement. Cilia are shorter and more numerous, while flagella are longer and fewer in number.
* Gap Junctions: These are specialized channels that allow for direct communication between neighboring animal cells.
Note: Plant cells do have other structures that animal cells do not, such as a cell wall, chloroplasts, and a large central vacuole.
