The major difference between plant cells and animal cells is the presence of cell walls in plant cells.

Here's a breakdown:

* Plant cells have rigid cell walls made of cellulose that provide structural support and protection. This allows plants to stand upright and maintain their shape.

* Animal cells lack cell walls and rely on internal cytoskeletal structures for support. This makes them more flexible and able to move.

While this is the most significant difference, there are other key distinctions:

* Chloroplasts: Plant cells have chloroplasts, which are organelles that carry out photosynthesis, converting sunlight into energy. Animal cells lack chloroplasts.

* Vacuoles: Plant cells typically have a large central vacuole that stores water and nutrients, while animal cells have smaller vacuoles.

* Centrioles: Animal cells have centrioles, which are involved in cell division, while plant cells typically lack them.
