Which kind of yeast ,young or old, is bigger? And why?

To determine which kind of yeast is bigger, we need to understand the process of yeast growth and how it relates to age.

When yeast is described as "young" or "old," it refers to its stage of growth. Yeast is a microorganism that reproduces by budding. During the budding process, a daughter cell forms and then separates from the parent cell.

So, if we compare a "young" yeast cell to an "old" yeast cell, we expect the young cell to be smaller since it has just recently budded from the parent cell.

To see the size difference between young and old yeast cells, you can perform a simple experiment.

1. Start by growing a yeast culture in a suitable medium (such as liquid broth or agar plates). Allow the yeast cells to grow at a stable temperature for a designated period (for example, 24 hours).

2. After the specified time, take a sample from the culture and prepare two slides: one with the young yeast cells and another with the old yeast cells. This can be done by diluting the yeast culture and placing a drop of each sample onto separate microscope slides.

3. Observe the slides under a microscope using a suitable magnification. Count and measure the size of yeast cells using an eyepiece graticule or image analysis software.

Through this experiment, you will be able to compare the size of the young and old yeast cells. However, it is important to note that the actual size of yeast cells can vary depending on various factors such as the yeast strain, environmental conditions, and nutrient availability.
