Cell wall structure Fungi cells
, like plant cells, are surrounded on the outside by a strong cell wall that supports the shape of the cell and protects it from damage. In most fungi, the cell wall consists of chitin, a substance that also forms an exoskeleton in insects, and only in oomycetes the main substance is cellulose. Outside, there are molecules of melanin pigment on the walls of some fungi. Also in the cell wall are lipids, proteins and polyphosphates.
In vegetative cells of some inferior fungi, the cell wall may be absent.
Cytoplasm and organoids
Inside the fungus cell are organoids and cytoplasm. Hereditary material is stored in the nucleus as well as in mitochondria, with nuclei in the mushroom cell being either one or more. If you consider the kernels of the family of fungi in more detail, you can find that this kingdom occupies an intermediate position between plants and bacteria: their DNA is half as small as that of plant cell, but larger than bacteria.
Of the other organoids, mitochondria are present in the mushroom cells involved in the oxidation of organic compounds and the release of energy molecules, the Golji apparatus involved in protein transport, formation of glycolipids, glycosaminglicans, proteolysis of proteins and sulfation of protein and carbohydrate compounds. The endoplasmic reticulum is also involved in the transport and accumulation of fusion products.
Also in mushroom cells there are ribosomes engaged in protein synthesis from amino acids and interacting with RNA using special sites. As in animal cells, the main stockable substance of fungi is glycogen. Also in fungi can be found and stocked lipid drops.
Some fungi in the cell have one or more small vacuoles where nutrients are deposited.
Between the cytoplasm surrounded by the cytoplasmic membrane and the cell wall are lomasoms—structures outwardly resembling small vesicles. Their appointment has yet to be clarified, however scientists suggest that lomasomes take part in cell wall formation.
The vast majority of fungal cells have no structures to provide them with the ability to move. However, movement organelles are necessary for cells involved in reproduction. Gametes and zoospores have smooth, perious, or bicycles.
