Which one of the following is a single cell fungi?

✅ Explanation: Yeasts are single-celled fungi that reproduce asexually by budding or fission. They are widely used in baking, brewing, and biotechnology.

📌 Other Options Explanations:
-Option B: Aspergillus: Aspergillus is a genus of filamentous fungi, meaning they are composed of many cells arranged in thread-like structures called hyphae.
-Option C: Penicillium: Penicillium is also a genus of filamentous fungi, known for their production of the antibiotic penicillin.
-Option D: Alternaria: Alternaria is yet another genus of filamentous fungi. They are common plant pathogens causing leaf spots and blights.

🔑Key Points:
-Single-celled fungi are known as yeasts.
-Yeasts can metabolize carbohydrates into alcohol and carbon dioxide.
-Fungi are a kingdom of mostly microscopic organisms that are closely related to animals.
-Some fungi will produce large ‘fruiting bodies’ called mushrooms that produce huge numbers of spores for reproduction.
-The cell walls of fungi are made from a compound called ‘chitin’.
Additional Information
-Molds belong to a group of fungi called zygomycetes.
-Molds are a kind of fast-growing fungi that are spoiling many foods such as bread, fruits, vegetables, and dairy products.
-Penicillium is a genus of blue or green mold fungi (kingdom Fungi).
-Species of Penicillium are recognized by their dense brush-like spore-bearing structures called penicillin.
-Mushrooms, or toadstools, are the fruiting body common to many species of fungi and are used to store and release spores into the environment.
-It is made from a collection of fungal cells called ‘hyphae’.
-Hyphae are woven together to produce a spore-bearing mushroom.
