Lets talk about these; have you ever left a slice of bread for many days? Did you notice some growths on the bread? What do we call these growths?
The pictures shows some organisms that belong to a group called fungi. Organisms in this group are different from plants and animals.
Organism-anything that is living.
Identify fungi in our local area
Draw fungi in your exercise book, find more images of fungi.
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.
