What structure did you see in both onion cell and cork cell?

Both onion cells and cork cells exhibit a distinct cell wall structure that provides rigidity and support. In onion cells, the walls are composed of cellulose and are more flexible, allowing for turgor pressure, while cork cells have a thicker, protective cell wall made of suberin, which gives them a more rigid and impermeable characteristic. Additionally, both cell types contain a central vacuole, which plays a role in maintaining cell turgor and storage. However, cork cells lack chloroplasts, unlike onion cells, which can have these organelles for photosynthesis.
