Which of the following is NOT an example of a member of the kingdom Fungi?

• A. Chlorella vulgaris (green alga)
• B. Saccharomyces cerevisiae (baker's yeast)
• C. Penicillium notatum (mold)
• D. Agaricus bisporus (button mushroom)

Answer: (A)

Verified step by step guidance

1. Step 1: Understand the characteristics of the kingdom Fungi. Members of this kingdom are eukaryotic organisms that include yeasts, molds, and mushrooms. They are heterotrophic, meaning they obtain nutrients by absorbing organic material, and their cell walls are primarily composed of chitin.
2. Step 2: Review the examples provided in the question. Saccharomyces cerevisiae (baker's yeast), Penicillium notatum (mold), and Agaricus bisporus (button mushroom) are all well-known members of the kingdom Fungi.
3. Step 3: Examine Chlorella vulgaris (green alga). Green algae are photosynthetic organisms that belong to the kingdom Plantae or Protista, depending on classification systems. They are not heterotrophic and do not have cell walls made of chitin, which distinguishes them from fungi.
4. Step 4: Compare the characteristics of Chlorella vulgaris with those of fungi. Since Chlorella vulgaris is photosynthetic and lacks fungal traits, it does not belong to the kingdom Fungi.
5. Step 5: Conclude that Chlorella vulgaris (green alga) is the correct answer to the question, as it is NOT a member of the kingdom Fungi.
