Fungi are eukaryotic heterotrophs that feed by absorbing nutrients from outside their bodies. They have cell walls composed of chitin and their multicellular forms grow as networks of filaments called hyphae that can form tangled masses called mycelium in soil. Fungi reproduce both sexually through the fusion of compatible hyphae to form zygotes and asexually through spores. Common types of fungi include zygomycetes, sac fungi, yeasts, club fungi and imperfect fungi.

1. Fungi

2. What are Fungi?
• Fungi grow from the ground once led scientists
to classify them as nonphotosynthetic plants
• they are not plants at all, fungi are very different
• Fungi are eukaryotic heterotrophs that have cell
walls

3. Chitin
• A complex carbohydrate that
makes up the cell walls of fungi

4. Fungi Nutrition
• Unlike animals, fungi do not ingest their food
• Instead they digest food outside their bodies and then
absorb it
• Many feed by absorbing nutrients from decaying matter
in the soil (decomposers)
• Others live as parasites, absorbing nutrients from their
hosts

5. Structure and Function of Fungi
• All fungi are multicellular with the exception of yeast
• Multicellular fungi are composed of thin filaments called
hyphae

6. Structure and Function of Fungi

7. Fungus Structure
• The bodies of multicellular fungi are composed
of many hyphae tangled together into a thick
mass called a mycelium

9. Fruiting body
• The reproductive structure growing from the mycelium in
the soil that you recognize as a mushroom

10. Fungi reproduction
• Most fungi reproduce both
• Asexually by spore
• Sexually by zygote
