The first was called multiplication by budding based on the biology of yeast cell propagation.
The second was multiplication by seedlings, based on the idea of a seed being caught by the wind and blown to a distant location.
Method 1: Multiplication by budding
A yeast cell multiplies by a process known as budding as shown in the diagram above.
A yeast cell that is about to bud has a predetermined area of the cell that becomes blown out forming a new cell, the so-called bud. (a)
The nucleus will divide with one nucleus migrating into the new cell. (b)
When the new cell is approximately the size of the original cell, the cells will seal off the opening and separate, giving rise to two yeast cells. (c)
The emphasis on this form of multiplication is that of geographical proximity and control whilst the new cell forms. The parent cell provides supervisory control over the child cell until it gets to a level of maturity.
