Question

How is it evident that robust mechanisms are present in yeasts which coordinate for cell division and growth?

Answer 1

Yeast:

1. Yeast is a unicellular eukaryotic fungus that reproduces asexually by budding.
2. Yeast cells can encounter sudden big changes in the nutrient levels in their environment and are expected to respond with widely varying rates of growth.
3. But the size of yeast cells changes relatively little in different conditions.
4. Consequently, it is clear that robust mechanisms are present in yeast for the coordination of cell division, and growth for the cell size is maintained within a narrow range in the face of much greater variations in growth rate.
