Bio 11 - Fungi

Eukaryotic

Heterotrophic--break down living or dead

organic matter, recycle nutrients through ecosystems

May be unicellular (yeast and mold)

Most are multicellular (mushroom)

Some fungi are edible while others are

poisionous

Characteristics of Fungi

Chitin

What are the cell walls of Fungi made up of?

Slightly acidic environments

Where do Fungi grow best?

Absorption of nutrients and reproduction

What are Fungi well adapted for?

Mycelium

A mesh of microscopic branching filaments found on or below the substrate.

Where nutrient absorption occurs

Hyphae

Each filament within the mycelium

Spores

Haploid cells that are produced in the sporangium for sexual reproduction.

Fragmentation

A method of asexual reproduction in fungi as the mycelium breaks apart

Plants are autotrophic while fungi are heterotrophic.

Plants have root systems fungi do not.

Cellulose in cell wall of plants. Fungi have chitin in their cell walls.

Only one nuclei per cell in plants often more than one nucleus in the cells of Fungi (dikarytoic)

Why are fungi not plants?

Substrate

A surface on or in which Fungi attach

Saphrophytes

Organisms that obtain nutrients from dead or non-living matter

Dikaryotic

Cells that contain two haploid nuclei each of which came from a separate parent

Haploid

A cell that has half of a full set of chromosomes

Diploid

A cell that has a full set of chromosomes
