Yes, onion root cells do have cellulose cell walls.
The cell wall, including that of onion root cells, is primarily composed of:
- Cellulose fibers: These provide strength and structure.
- Pectins: These contribute to cell adhesion.
- Hemicelluloses: These are chemically diverse and play a role in cell wall flexibility.
The referenced information confirms that cellulose is a key component of the cell wall.
