Moulds, yeasts, puffballs, and mushrooms are examples of fungi. Toadstool is an example poisonous fungi.
Importance of fungi to human beings
- – yeast is added to dough in bread making. This produces a gas that makes the dough to rise and swell.
- . Some farmers grows mushrooms. They sell mushrooms to earn living. Edible mushrooms are rich in proteins and vitamins.
- Manufacture of medicine. Some fungi are used to make medicine. For example, fungus called penicillium is used to make pencillin.
- Improving soil fertility. Fungi like mushrooms that grows on dead matter speed up the rate of decomposition. When dead matter decompose, it forms humus, which improves soil fertility.
- Some fungi grow on stems and roots of some plants. Such fungi helps the plants roots to absorb water and mineral salts from the soil.
Decompose-to rot or decay.
Dough- a thick mixture of flour and water used for baking bread.
Edible-safe to be eaten.
Fungi cause three different types of human illness: poisonings, parasitic infections, and allergies. Many poisonous mushrooms are eaten by mistake because they look like edible mushrooms. Parasitic yeasts cause candidiasis, ringworm, and athlete’s foot. Mold allergies are very common.
