NEET BIOLOGY

Detailed explanation-1: -Yeasts are defined as unicellular fungi. The idea of a unicellular organism carries with it the notion of being ‘free-living’. The concept of a free-living unicellular organism is very valuable because it should be a good model for the study of intracellular processes.

Detailed explanation-2: -Yeasts are mostly unicellular, but they live in multicellular colonies. Within the Kingdom of Fungi, yeast is a polyphyletic group of species. Although many yeasts are known to switch between unicellular and multicellular lifestyles depending on environmental factors, we classify them as facultatively multicellular.

Detailed explanation-3: -Unicellular fungi are generally referred to as yeasts. Saccharomyces cerevisiae (baker’s yeast) and Candida species (the agents of thrush, a common fungal infection) are examples of unicellular fungi.

Detailed explanation-4: -Within the Kingdom of Fungi, yeast is a polyphyletic group of species. They are mostly unicellular.

Detailed explanation-5: -“Yeast is a fungus that grows as a single cell, rather than as a mushroom, ” says Laura Rusche, associate professor of biological sciences. Though each yeast organism is made up of just one cell, yeast cells live together in multicellular colonies.
