A microscopic view showcasing cells arranged in layers, featuring various shapes and sizes. Predominantly pinkish-purple hues with darker circular structures scattered throughout suggest staining techniques often used in biological imaging. The image has clear, defined boundaries with a white background separating the sections.

A petri dish containing various colonies of bacteria and fungi, showcasing diverse shapes, sizes, and colors. The colonies are growing on a nutrient agar medium with a grid pattern beneath them. Some colonies are circular and smooth, while others have fringed or filamentous edges. The dish is viewed from above, displaying a layer of translucent medium and different colony morphologies.
