What does yeast look like when it is fully grown?

When fully grown, yeast typically appears as small, round or oval-shaped cells, often measuring about 5-10 micrometers in diameter. Under a microscope, they may show a smooth surface and can be seen budding, which is a common method of reproduction for yeast cells. In larger cultures, they can form a creamy or frothy layer on the surface of liquids, and they may also produce sediment at the bottom of containers. Overall, they can be pale yellow or off-white in color, depending on the type of yeast.
