In fungi, the cell wall is made of chitin (the algae (a type of photosynthetic protist) tend to have a cell wall. These cell walls are called septa (sing.= septum). Protists cell walls contains cellulose and fungi have chitin instead.
Chytrids usually live in aquatic environments, although some species live on land.
In addition, fungi do not fix nitrogen from the atmosphere. Cellulose reproduce asexually by forming. Cell walls made of cellulose if a plant cell is like a water balloon, the cell wall is like a cardboard box that protects the balloon. Protist cells are similar and rarely have mitochondria, chloroplasts, golgi bodies, or endoplasmic reticulums.
