    Hello and welcome to Fungi. After listening to this lecture, I hope you'll be able to define the two different types of fungi. I hope you'll understand how yeast reproduce and what we can use them for. I want you to be familiar with the structure of filamentous fungi and I want you to know some diseases that are associated with fungi. There are two types of fungi in general. Most of the fungi that we know are called filamentous. They form large networks of filaments that are called mycelia, and that is shown in this slide, and the mycelia in turn are made of smaller segments called hyphae. And this, you should be familiar with, if you've ever had moldy food in your house, bread or fruit that's covered with a fuzzy layer, that is a filamentous fungus. Mushrooms are also fungi, even though they are not microscopic, they are part of a very large mycelium. Remember that mycelium is the network of filaments that makes up the filamentous fungi, this typically grows underground. The mushrooms are actually aggregates of the mycelium that come up above the ground and they drop spores onto the ground to make more fungi. So the mushroom is big, it is not a microbe because you can see it, but it's obviously part of a microorganism, the fungus. The other kind of fungus are called yeasts, and this is because they are single cell and there is a diagram of single cell yeast here and a photograph of real yeast cells which are dividing. This particular yeast happens to be Saccharomyces cerevisiae. So we have filamentous fungi and yeast type fungi. Now an important property of all the fungi, is that they are heterotrophs, they acquire food by absorbing small molecules, they can't make...
