Kingdom Fungi
What are some fungi
• Molds
• Lichens
• Mushrooms
There is a fungus among us!
• Fungi are everywhere:– Cheese– Mold– Athlete’s Foot– Food – edible Mushrooms– Poisonous Mushrooms
Mushrooms examples
• During the summer you may see them sprout up in your yard.
• Especially after a long-term rainstorm in the summer.
Edible Mushroom
• This is a morel mushroom.
Yeast
• unicellular• Reproduce asexually by cell splitting or
budding
What are the structures of a fungus?
• Fungus body• Hypha (pl.=Hyphae)
• Mycelium (pl.=Mycelia)• Gills in mushrooms
Branching, threadlike tubes that make up the bodies
Cap
Stalk
How are they similar to other organisms?
• Presence of cell wall: Chitin • Eukaryotes: organelles, e.g. nuclei,
mitochondria, membranes
How do fungi eat?With a knife and fork? NO! They are
decomposers!Enzymes (chemicals) are given off by the fungus The enzymes breaks
down the material the fungus is growing on into food.
The food is then digested by the enzymes.
The digested food is then absorbed by the fungus.
Heterotroph or autotroph?
• They get their food from another source so they are Heterotrophs.
How do Fungi reproduce?
• Reproduce by spores (Asexual)
• Sexual reproduction by hyphae tubes mixing genetic material.
They can in two ways:
Bad things caused by fungi:
• Ringworm
• Athlete’s Foot• Under toenails and fingernails.
Uses of fungi:
• Food - cheese, eating mushrooms themselves.
• Medicines - Penicillin
Summary of Characteristics• Eukaryotes• Body composed of hypha, mycelium or yeast, or
both.• Reproduce asexually by spores • Cell Wall, usually of chitin• Most multicellular • Unicellular = yeast• Heterotrophs.– Mode of nutrition – absorption
