1. Cell wall: The cell wall of the fungus is strong and strong. It is composed of chitin, cellulose and glucan. Besides, it contains callose, lignin and other organic substances. It preserves the protoplast.
2. Plasma membrane: The thin membrane inside the cell wall is called plasma membrane. It is composed of lipids and proteins. Between the cell wall and the plasma membrane there are small granular vesicles or tubular structures. It is called Lomasom. Argosterol is one of the components of fungal cell membrane.
3. Cytoplasm: All the living parts of the cell inside the cell wall are called cytoplasm. It is composed of a colorless, granular and jelly-like substance. It contains lysosomes, ribosomes, endoplasmic reticulum, mucus etc. It contains glycogen and fat as stored food. However, photosynthetic pigments are absent.
4. Nucleus: Fungi are unicellular organisms. Its cells have a well-formed nucleus. Nucleus of hyphae is small and nucleus of germ cell is large. Fungal cells are monokaryotic if they have one nucleus, dikaryotic if they have two nuclei and heterokaryotic if they have many nuclei.
5. Cell vacuole: Fungi have a large vacuole or numerous tiny vacuoles. Normally old cells contain cells. Cell cavity contains amino acids, hydrolase etc.
6. Plectenchyma: The hyphae of some fungi join together to form the fungal tissue. This is called the platenchyma.
