FUNGI
Mushrooms, Puffballs, lichens, yeasts, and molds that grow on foods all belong to a special group of living things called fungi. Members of the fungi kingdom are neither plants nor animals. They absorb their food through networks of thin feeding threads.
Fungi were once thought to be plants, because many grow from the soil and do not move. Scientists now know that fungi and plants are very different. Unlike plants, fungi are not green and do not make their own food. Most fungi feed on dead animals and rotting plants. New fungi grow from tiny balls, called spores, which are released into the air.
Structure of a Mushroom
A mushroom has a stem, cap, and gills that produce spores. The cap is held above the ground so that escaping spores can be carried away by air currents. At the bottom
of the stem are slender threads, or hyphae, that search for food.
Fungus Varieties
There are about 65,000 known types of fungi. They grow in soil, among leaf litter, on dead trees, and on living plants.
Mushroom Life cycle
1.Tiny spores released by a mushroom float away in the air.
2. A mass of hyphae gr
ows under the ground from the spores.
3. above the soil, hyphae pack together to form a “button” mushroom.
4. A mushroom grows up and is soon ready to make new spores.
Fungi and Alga
A lichen is a joining of a fungus and a plantlike alga, which live together as one organism. The fungus protects the alga, and the alga makes food for the fungus. Lichens grow on rocks and tree trunks.
Poisonous Mushrooms
Some mushrooms contain poison to stop animals from eating them. This is why you
Should never pick mushrooms in the wild. No matter how colorful and pretty they look, they could be highly dangerous.
