Draw and describe a typical fungal cell
Answers
Answer:
fungal call wall are made up of citin
Answer:
Fungi are eukaryotes with a complex cellular organization.
As eukaryotes, fungal cells contain a membrane-bound nucleus where the DNA is wrapped around histone proteins. Fungal cells also contain mitochondria and a complex system of internal membranes, including the endoplasmic reticulum, ribosome and Golgi apparatus.
Explanation:
- Fungi are achlorophyllous, non-vascular, spore-bearing unicellular or multicellular thick-cell-walled heterotrophic thallophytes.
- They are known as decomposers that eat decaying matter and make tangles of filaments.
A typical Fungal Cell structure:
1. The fungal cell wall is rigid and composed of complex polysaccharides "chitin" (fungal cellulose, C₂₂H₅₄N₄O₂₁ this adds structural strength) and "glucans."
2. In primitive fungi, true cellulose with or without chitin is found.
3. Plasmalemma bears occasional coiled ingrowths called "lomasomes" which lie below the cell wall.
4. The cytoplasm contains organelles such as the Endoplasmic reticulum (ER), mitochondria, ribosome, Golgi bodies etc. and inclusion bodies (stored foods, pigments and secretory granules).
5. The cytoplasm at the hyphal tip contains Golgi vesicles called "chitosomes" which are filled with cell wall materials.
6. The nucleus and mitochondria are found to connect with the endoplasmic reticulum.
7. The nucleus divides by intracellular mitosis called "karyokinesis" where the nuclear envelope remains intact during nuclear division and the internal spindle develops.
8. Reserve food (Storage granules) is glycogen and oil.
