What is yeast made from?

A spoonful of yeast is actually a teeming colony of tiny plants  They are living things and all living things come from other living things  For life can only be handed on from generation to generation ‑ we cannot make a new living thing  However, we can provide the tiny yeast plants with lush living conditions so that they multiply at a great rate,

With warmth and water, a oolong of yeast cells will double itself in 20 minutes and quadruple itself in less than an hour  Yeast for the market is grown in great vats where conditions are dust right, A single yeast is a one‑celled plant  When it has food and everything it needs, it produces a daughter cell in maybe 15 minutes, The daughter cell can produce a daughter in the next 15 minutes, meantime the first cell is producing another daughter of its own, This fast multi  plication continues as long as the right conditions last
