• What is one way that fungi are beneficial to humans?

Fungi

The male party animal!!!

Let’s see what you remember.

• Write the answers to the following questions in the margin of your notes.

• Are fungi eukaryotic or prokaryotic?• Are fungi consumers or producers?• Are fungi unicellular or multicellular?

General characteristics

• So, eukaryotes or prokaryotes?

• All fungi are eukaryotes. (#1)

• I forget, what does this mean?

• They have a nucleus.

General Characteristics

• Consumers or producers?• consumers

• Fungi must live on or near their food because they must absorb their food after secreting their digestive juices on their food. (#2)

General Characteristics

• Many fungi get their energy from dead plants or animals.

• What do we call organisms that get their energy from dead things?

• Decomposers are organisms that get their energy from dead organisms.

General Characteristics

• Unicellular or mulitcellular?

• Actually, fungi can be unicellular or multicellular, but most fungi are multicellular. (#6)

General Characteristics

• Multicellular fungi are made up of hyphae.• Hyphae: chain of cells that forms a

filament that is similar to a plant.

• The hyphae grow in a twisted clump called the mycelium, which is the major of the fungus. (#12)

Threadlike Fungi

• Shapeless, fuzzy fungi that are usually decomposers• Asexual reproduction: sporangia form at the tips of the

hyphae (threads) and release spores (#4)• Sexual reproduction: two hyphae from separate fungi

join and forms spores (#5)

Sac Fungi

• Mildew, yeast, truffles, morels• Sexual reproduction: formation of a sac called an ascus.

Spores form inside the ascus (#8)• Yeast: unicellular and reproduces asexually by budding

in which a new yeast cell pinches off the old one (#9)

Club Fungi

• Includes mushrooms• Sexual reproduction: hyphae develop into

clublike structures called basidia. Spores develop inside the basidia (#14)

Imperfect Fungi

• These fungi do not fit into any of the other three categories of fungi. (#19)

• Only reproduce asexually.• Many are parasites including the fungus

that causes athletes foot and aflatoxin which can cause cancer.

• Penicillium: the source of the antibiotic penicillin (#20)
