How Do Fungi Populations Grow and Survive? Starring:

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.

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. i.e.: SUGAR = C6H12O6

Molecules SUGAR = C6H12O6

Molecules SUGAR = C6H12O6 How many carbon atoms?

Molecules SUGAR = C6H12O6 How many carbon atoms? 6

Molecules SUGAR = C6H12O6 How many carbon atoms? 6 How many hydrogen atoms?

Molecules SUGAR = C6H12O6 How many carbon atoms? 6 How many hydrogen atoms? 12

Molecules SUGAR = C6H12O6 How many carbon atoms? 6 How many hydrogen atoms? 12 How many oxygen atoms?

Molecules SUGAR = C6H12O6 How many carbon atoms? 6 How many hydrogen atoms? 12 How many oxygen atoms? 6

Molecules Carbon Dioxide = CO2

Molecules Carbon Dioxide = CO2 How many carbon atoms?

Molecules Carbon Dioxide = CO2 How many carbon atoms? 1

Molecules Carbon Dioxide = CO2 How many carbon atoms? 1 How many hydrogen atoms?

Molecules Carbon Dioxide = CO2 How many carbon atoms? 1 How many hydrogen atoms? 0

Molecules Carbon Dioxide = CO2 How many carbon atoms? 1 How many hydrogen atoms? 0 How many oxygen atoms?

Molecules Carbon Dioxide = CO2 How many carbon atoms? 1 How many hydrogen atoms? 0 How many oxygen atoms? 2

Molecules Alcohol = C2H5OH

Molecules Alcohol = C2H5OH How many carbon atoms?

Molecules Alcohol = C2H5OH How many carbon atoms? 2

Molecules Alcohol = C2H5OH How many carbon atoms? 2 How many hydrogen atoms?

Molecules Alcohol = C2H5OH How many carbon atoms? 2 How many hydrogen atoms? 6

Molecules Alcohol = C2H5OH How many carbon atoms? 2 How many hydrogen atoms? 6 How many oxygen atoms?

Molecules Alcohol = C2H5OH How many carbon atoms? 2 How many hydrogen atoms? 6 How many oxygen atoms? 1

What happens to make bread rise? Fermentation reaction:

What happens to make bread rise? Fermentation reaction: Sugar carbon dioxide + alcohol Yeast

What happens to make bread rise? Fermentation reaction: Sugar carbon dioxide + alcohol C6H12O6 2CO2 + 2C2H5OH Yeast Yeast
