1. Cell Wall: This rigid outer layer is made primarily of cellulose, and it provides the cell with its shape and strength. It acts like a protective barrier, helping the plant to withstand internal pressure and maintain its form.
2. Cytoskeleton: This network of protein filaments extends throughout the cytoplasm. It provides support and helps with cell movement, division, and the transport of materials within the cell.
While other components like the vacuole contribute to cell shape and turgor pressure, the cell wall and cytoskeleton are the primary structural components of a plant cell.
