Yeast

Yeast

• Is it alive or not?

Yeast

• Is it alive or not? –Lets revisit our characteristics of

life.

Yeast

• Characteristics of life:

Yeast• Characteristics of life:

–Cells (unicellular- thick cell wall, no hyphae)

–Responds–Grows–Reproduces–Uses energy/ gives off waste

How does it reproduce?

• Not by spores

• It’s called budding

• It “pinches” off

Yeast and Bread

• Why does bread rise?

Yeast and Bread

• Why does bread rise?

• It involves a little bit of chemistry.

• The periodic table of elements = 100+ “ingredients” of the universe

Elements• C= Carbon

Elements• C= Carbon

• H= Hydrogen

Elements• C= Carbon

• H= Hydrogen

• O= Oxygen

Elements• C= Carbon

• H= Hydrogen

• O= Oxygen

• Molecules are the smallest combination of elements that make up something that is not a pure element on the chart.
