Living(BIOTIC) - organisms must have all 7 characteristics of life(living and dead).
Nonliving(ABIOTIC) - things do not have all 7 characteristics.
Dead – organism once had the 7 characteristics of life but now doesn’t. It is Considered to be LIVING!!!!
How would you know if this is living?
Yeast
• The tiny, rounded, colorless one-celled fungus called yeast floats through the air everywhere, but it is responsible for making all our cakes and breads rise to a nice, fluffy texture. This happens because yeast creates chemical reactions on the starch and sugar in the cake or bread batter. Here’s how it works.
• Yeast cells reproduce very rapidly no matter where they are. This reproduction goes on through a process called budding. In budding, each tiny cell swells, and soon the swollen part separates from the main cell. The new tiny cell then goes on to grow to full size on its own and the budding process continues to repeat itself.
• During this growth process, the yeast cells produce substances called enzymes. So when the yeast is added to cake or bread dough, one enzyme goes to work on the flour, changing the starch in it into sugar.
• Another enzyme then takes over and changes the sugar into alcohol and a gas called carbon dioxide. This gas spreads through the dough in the form of bubbles.
• As the dough bakes into bread and cake, the heat causes the alcohol to evaporate and the bubbles to break. This leaves the tiny air pockets in the final bread or cake, making it light and fluffy.
Yeast and Fungus kingdom• Not Plants – produce enzymes that digest
their food outside their bodies.
• Some are parasites/
• Cell walls – contain chitin
• Fungi are heterotrophic eukaryotic with cells walls that contains chitin.
Fungi Structure2 basic structures
1. Yeast – singled celled
2. Mushroom – multi - celled that grow much larger with hyphae
Reproduction of FungusFungus can reproduce sexual and asexual
Spores(asexual) – Spores are just reproductive cells.
Sexual – Sperm and egg combine to form a zygote.
Roles in Ecosystem1. Decomposer – break down plant material.
2. Parasite – Infect plants and animals(ringworm).
3. Animal disease
4. Lichens – Mutualistic relationship between a photsynthetic organism and a fungus. Plant makes the energy and fungus breaks down the nutrients in the environment and they share.
