**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<u> volume determines how much cytoplasm a cell has</u>, 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 <u>surface determines how much plasma membrane a cell has</u>, 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.**
