Answer: A mature parent cell is approximately 4 µm, while a budding cell is 3 µm. Since the shape of a yeast is a sphere, we can use the formula below:
V= (4/3)π.r³, considering that π=3,14 and r is for ratio of the sphere, which is half of it's diameter.
For a parent cell, the volume is: 33 µm³
For a budding cell, the volume is: 14 µm³
Since the volume determines how much cytoplasm a cell has, then a budding cell needs to grow the mature parent cell - its own current volume, so the result would be 19 µm³ of cytoplasm.
To calculate the surface area, we use another formula that is presented below:
A= 4.π.r²
For a parent mature cell, the surface is 50 µm²
For a budding cell, the surface is 28 µm²
Since the surface determines how much plasma membrane a cell has, to know how much the budding cell needs to grow up to a mature state is simply using the surface area of the parent cell - the current surface area of it, resulting in 22 µm².
