Yesterday we learned that Yeast likes to eat
Sugars. It eats sugars in bread dough and
begins carrying out life processes. This causes
the bread to rise.
Let me get you started...Yeast are
Heterotrophs, so they need to eat other
things.
How might these pictures help you explain how
Yeast makes bread rise. Think of our
Experiment Results...
Yeast is a Heterotroph and eats
Sugars. With all the right conditions present moisture, warmth, and food - the yeast
eventually excretes Carbon Dioxide Gas
as waste. The carbon dioxide gets trapped in the
sticky dough, causing the dough to rise.
Then how is this possible?

3) Good to eat
4) Decomposers break down dead things
5) Yeast makes bread rise
6) Yeast used in beer brewing
7) Used in the production of Coca Cola
8) Symbiosis with grass gives grass a
"bionic" root system
Negative Effects of Fungi in Our World
Discuss how these show
negative affects of fungi on us
