Fungal cell pictures Biology Diagrams Unicellular fungi (yeasts) cells form pseudohyphae from individual yeast cells. In contrast to molds, yeasts are unicellular fungi. The budding yeasts reproduce asexually by budding off a smaller daughter cell; the resulting cells may sometimes stick together as a short chain or pseudohypha (Figure \(\PageIndex{1}\)).
Many of the mechanisms that control the cell cycle were worked out in fungal cells, taking advantage of their powerful genetics and rapid duplication times. The critical insight made by researchers working with fungi in the late 1970s and early 1980s was that distinct cell morphologies could serve as landmarks in-dicating cell cycle stage.

The science dealing with the study of fungi is called "Mycology".A thallus refers to the fungal cell body, which can be either unicellular (yeasts) or multicellular (moulds).. Some fungi show dimorphism between the two states by following both yeast and mould cell cycle and called "Dimorphic fungi". In this context, we will discuss the structure of fungi by looking into the diagram and
1. Fungi are composed of Eukaryotic cells. Cells with a nucleus and organelles are a common feature of Eukaryotic cells. What is unique about many fungi is that they can maintain two distinct nuclei per cell. Also, some fungi appear to have lost their mitochondria, the organelle responsible for aerobic respiration (using Oxygen to generate ATP). 2.

Unlike plant cells, fungal cells do not have chloroplasts or chlorophyll. Many fungi display bright colors arising from other cellular pigments, ranging from red to green to black. The poisonous Amanita muscaria (fly agaric) is recognizable by its bright red cap with white patches (). Pigments in fungi are associated with the cell wall and play The Fungal Body. Fungi have well-defined characteristics that set them apart from other organisms. Most multicellular fungal bodies are made up of filaments called hyphae.Hyphae can form a network called a mycelium, which is the thallus (body) of the fungus (Figure \(\PageIndex{1}\)).Fungi are heterotrophs that excrete enzymes to digest food externally, then absorb the digested food.
