What Are Fungi?
Fungi are a unique life form. Fungi vary in size and shape.
Some fungi are unicellular
and others are multicellular.
They are eukaryotic, heterotrophic
decomposers that live in moist,
warm environments and reproduce by spores.
Structure
All fungi, except for yeast, are composed of structures called hyphae.
These hyphae are branching, threadlike tubes that make up the entire
fungal body.
Fungi vary in size and shape. Most of us have seen fungi growing
on the side of trees or on the ground as we take a walk through the woods.

How Do Fungi Obtain Food?
Fungi feed by absorbing food through the hyphae. They do this
by the following method:
-
The fungus grow hyphae into a food source.
-
Digestive juices ooze from the tips of the hyphae.
-
These juices break down the food.
-
The hyphae then absorb the dissolved food.
Some fungi break down decaying organisms. Others live as parasites
on other living organisms. Athlete's foot is an example of fungus
that grows on a person's skin.
