Fungi - Tissue and Cell Structure

Description:

If the mycelium of fungus gets organized into loosely or compactly woven tissue like structure it is called plectenchyma.

When mycelium is loosely interwoven and lie more or less parallel to each other then it is called prosenchyma.

When hyphae or the mycelium are very loosely packed then they are known as pseudoparenchyma.

Aseptate Hyphae − When the protoplasm in the hyphae is continuous i.e. without any cross walls of septa they are called aseptate.

Septate Hyphae − It the protoplasm of the hyphae is interrupted by the presence of hyphae then they are called septate.

The cell wall of hyphae is made up of fungus cellulose along with chitin. Protoplast is enclosed by the cell wall. The protoplast is covered by a thin semi-permeable plasma membrane. Cytoplasm contains many small vacuoles filled with cell sap. The hyphae may have mitochondria, golgi bodies, ribosomes, endoplasmic reticulum etc.
