Final answer:
The micrograph shows budding Saccharomyces cerevisiae yeast cells, which can communicate by releasing a signaling molecule called mating factor. The cells are visualized using differential interference contrast microscopy, a light microscopy technique that enhances contrast. Yeast cells are unicellular fungi that resemble bacteria in form and size.
Step-by-step explanation:
The micrograph of yeast cells in question shows budding Saccharomyces cerevisiae yeast cells. These yeast cells can communicate by releasing a signaling molecule called mating factor.
Microscopy techniques, such as differential interference contrast microscopy, were used in this micrograph to enhance the contrast of the sample, allowing for better visualization of the cells.
The yeast cells typically have a spherical shape and are around 5 um in diameter. They are unicellular fungi that have a cell wall composed of chitin and possess a nucleus and organelles like mitochondria, similar to bacteria.
