Question
Why do you think yeast mass increases rapidly initially and then plateaus (remains the same)?
2 marks
Solution
Yeast mass increases rapidly initially due to the process of reproduction. Yeast reproduces asexually through a process called budding, where a new organism grows on another one. In the initial stages, when there is an abundance of food and favorable conditions, yeast cells reproduce rapidly, leading to a quick increase in mass.
The plateau phase occurs when the yeast population reaches the carrying capacity of its environment. This is the maximum population size that the environment can sustain indefinitely. At this point, the rate of yeast reproduction equals the rate of yeast death, leading to a stable population size. The plateau can also be due to the depletion of resources, accumulation of waste products, or both, which inhibits further growth.
