Wake-up

1. How would you recognize an Amoeba?

2. How would you recognize euglena?

3. How would you recognize a paramecium?

What do you think of when you hear, Fungus?

Fungus Habitat

Fungus can be found anywhere where it is humid, damp, and warm

Fungal Structure

Fruiting body is the asexual reproductive structure of Fungus

Fungal Structure

The bulk of a fungus is underground; made up of a mass of fibers called

Mycelium

Mycelium is underground

Fungal Structure

The individual small strands that make up the Mycelium are called Hyphae

Fungal Structure Stop Video at 1:06

Fungus cells: Share all the same components as an Animal cell, BUT it has a cell wall for

structure and support

Fungal Feeding

Fungus are heterotrophs; consume their own food.

BUT mushrooms do not have mouths!!!!

How do they consume?

Fungal Feeding

Mycelium grows into whatever they need to consume; secret digestive enzymes which liquefies their food; and absorbs “juices”.

Fungal Feeding Strategy #1

Saprophytic – Fungus are decomposers; they consume dead organic material

Fungal Feeding Strategy #2 (Planet Earth 26:57)

Parasitic – Feed on living organisms; benefits at the expense of the host

Fungal Feeding Strategy #3Life: Insects 43:37

Mutualistic – Fungus and another organism that live and benefit from each other; in some

cases, couldn’t live without the other

Wake-up

1. How are Fungus plant-like?

2. How are Fungus animal-like?

3. Explain how Fungus obtain nutrients.

Fungus Reproduction: Spores

A reproductive structure that is

adapted for dispersal and

surviving for a long time in unfavorable

conditions; requires no fertilization

Spores can be dispersed by WIND

Spores can also be dispersed by

WATER or

by ANIMALS

Fungus Reproduction: Budding

Unicellular cells form new individuals from outgrowths (buds) on their “bodies”.

Fungus Reproduction: Fragmentation

A piece of the parent is broken into fragments (pieces); each of those pieces are able to

grow into a new organism.

Fungus Reproduction: Sexual

Fungus have specialized hyphae (“male” and “female”) that join; exchange gametes; and

grow a new fruiting body.

Wake-up

1. Explain the difference between reproduction with spores and reproduction with fragmentation.

2. What is the benefit of sexual reproduction in any organism?

Fungus Diversity: Truffles

Grow underground (saprophytic); spread their spores by depending on fungivores (animals

that eat fungus)

Humans hunt for Truffles; need the help of animals because they grow underground

Better known as the “Diamonds of the Kitchen”

European white truffles can sell for as much as $3,600 a pound, making them and their fellow fungi

the most expensive food in the world. One two-pound truffle recently sold for more than $300,000.

Fungus Diversity: Octopus Stinkhorns

Grow in decaying organic matter (saprophytic)

fungus)

Has a pink color and smells like rotten meat to attract flies; They help disperse their spores

Fungus Diversity: Glow in the Dark Mushroom

Grow on decaying matter; Saprophytic

They glow to attract nocturnal organisms to help spread their spores

Plus, you can grow them at home!!!!
