What is a Fungus?

Not a plant!!!– Heterotroph - No chlorophyll

therefore a– Saprobe – feeds on dead or

decaying matter

Eat by absorbing nutrients (decomposer)

– extracellular digestion, - Use hyphae for digestion that takes place outside of the body.

– Enzymes that break down nutrients then it is absorbed. (plants do not absorb nutrients)

Nutrition (Gets its food: )

Symbiosis

- Two organisms live in association together– Types of Symbiosis

• Mutualism• Parasitism• commensalism

Page 7: Chapter 23: Fungi Fungus Diversity Identify what fungi are. Describe habitats of fungi. Outline the structure of fungi. Describe fungi reproduction

Parasitic Fungus

Page 8: Chapter 23: Fungi Fungus Diversity Identify what fungi are. Describe habitats of fungi. Outline the structure of fungi. Describe fungi reproduction

- Parasite - live off of living organism Ex. athletes foot

- extracellular digestion

What it looks like under skin.

Ringworm

Mutualistic Fungus

Lichens and Mycorrizae

Page 13: Chapter 23: Fungi Fungus Diversity Identify what fungi are. Describe habitats of fungi. Outline the structure of fungi. Describe fungi reproduction

Lichens

- mutualism between a fungus and an algae- fungus- moisture, algae- food- Pioneer- one of first organisms to move into an areaenvironmentally sensitive

Page 14: Chapter 23: Fungi Fungus Diversity Identify what fungi are. Describe habitats of fungi. Outline the structure of fungi. Describe fungi reproduction

Mutualism: Lichen

Page 16: Chapter 23: Fungi Fungus Diversity Identify what fungi are. Describe habitats of fungi. Outline the structure of fungi. Describe fungi reproduction

Mycorrhizae

- mutual relationship between plant roots and fungi (90%)- increase absorption ability of roots

fungus benefit - nutrients and water

Structure of Fungus

• Cell wall made out of Chitin

Hyphae- reproductive filamentsMycelium- visible mass of hyphae

• Ex.Mushroom

Page 19: Chapter 23: Fungi Fungus Diversity Identify what fungi are. Describe habitats of fungi. Outline the structure of fungi. Describe fungi reproduction

-

- Hyphae and a mycelium

Page 20: Chapter 23: Fungi Fungus Diversity Identify what fungi are. Describe habitats of fungi. Outline the structure of fungi. Describe fungi reproduction

Reproduction of Fungus

Asexual – Fragmentation ,budding, – Produce spores

Page 21: Chapter 23: Fungi Fungus Diversity Identify what fungi are. Describe habitats of fungi. Outline the structure of fungi. Describe fungi reproduction

Spores

Page 22: Chapter 23: Fungi Fungus Diversity Identify what fungi are. Describe habitats of fungi. Outline the structure of fungi. Describe fungi reproduction

- Sporangium

- structure producing spores- sexual reproduction- 3 types- basis of classification

Page 23: Chapter 23: Fungi Fungus Diversity Identify what fungi are. Describe habitats of fungi. Outline the structure of fungi. Describe fungi reproduction
Page 24: Chapter 23: Fungi Fungus Diversity Identify what fungi are. Describe habitats of fungi. Outline the structure of fungi. Describe fungi reproduction

Adaptations

- spores- resistant- spores carried everywhere- huge numbers- puffball= trillion spores- warm, moist conditions

Page 25: Chapter 23: Fungi Fungus Diversity Identify what fungi are. Describe habitats of fungi. Outline the structure of fungi. Describe fungi reproduction

Zygote Fungus

Phylum – ZygomygotaExample: Bread MoldSpores are made by both asexual and sexual repro.Sexual Reproductive structure:– Sporangium

Distinct structures of:– Rhizoids – hyphae that

anchor the fungus– Stolon – mycelia that grow

along the surface

Page 26: Chapter 23: Fungi Fungus Diversity Identify what fungi are. Describe habitats of fungi. Outline the structure of fungi. Describe fungi reproduction

Note Rhizoids and Stolons:

Page 27: Chapter 23: Fungi Fungus Diversity Identify what fungi are. Describe habitats of fungi. Outline the structure of fungi. Describe fungi reproduction

You are looking at sporangia – contains spores

- Ascus – reproductive structure in sac fungus

- spore producing sac- sexual reproduction

Club Fungi- Basidiomycota

- mushrooms, puffballs, brackets, rusts and smuts, toadstools

Page 34: Chapter 23: Fungi Fungus Diversity Identify what fungi are. Describe habitats of fungi. Outline the structure of fungi. Describe fungi reproduction

- Basidia

- spore producing structures- gills, cap, stipe

- only sexual reproduction

Imperfect Fungi

Asexual reproduction onlyExamples:Penicillium – Aspergillus – used to

make soy sauce and citric acid

– Thrush – fungal infection of mouth

Importance of Fungi

1. Decomposers- recycle dead materials along with bacteria

2. Penicillin – antibiotic3. rich in vitamin C 4. Food source-5. Pest control – create competition, parasite to insects that eat crops
