Yes, fungi cells do have a cell wall. It's a rigid structure that surrounds the cell membrane and helps maintain the cell's shape and protects it from osmotic pressure.

The main sugar in fungal cell walls is chitin, a long-chain polymer of N-acetylglucosamine.

Here are some other points about fungal cell walls:

* Chitin: This is the most abundant component of fungal cell walls, giving them their structural strength.

* Glucans: These are polysaccharides, often linked to chitin, providing additional structural support.

* Other components: Fungal cell walls can also contain small amounts of proteins, lipids, and pigments.

* Differences between fungal cell walls and plant cell walls: While both contain polysaccharides, fungal cell walls are primarily composed of chitin, whereas plant cell walls are made of cellulose.
