Why does s. cerevisiae produce a sample with cells colored purple, pink, brown, and green? explain why this organism produced results that deviate from typical purple or pink gram-stained cells.

Saccharomyces cerevisiae (S. cerevisiae) is a species of yeast.  It is basically used in food production such as brewing , winemaking, and baking.

S. cerevisiae is used in gram staining, a technique that is used to differentiate two different groups of bacteria on the basis of different cell wall constituents.

Due to variation in the cell wall of S. cerevisiae, it doesn’t contain any lipid layer in its cell wall unlike bacteria. When primary stain and secondary stain are used during gram staining, it turns into several colors like purple, pink, brown, and green. That is why S. cerevisiae gives gram positive and gram negative effects both.

here is the answer

water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. weathering is the breaking down or dissolving of rocks and minerals on earths surface. once a rock has been broken down, a process called erosion transports the bits of rock and minerals away.
