While we can see some of the funguses some are too small to see with bare eyes. We call the funguses that we can see with the eyes “parasol mushrooms” and the “cultivated mushrooms” we eat at home is one of them. Foods such as bread and pastries, which we love to eat in daily life, are so delicious thanks to mushrooms, and we call these mushrooms “yeast funguses”. We also multiplied yeast fungus with our 5th grade students and learned what fungus they need in order to reproduce.
