1

Are fungi prokaryotic or eukaryotic

- eukaryotic

2

Eukaryotic organisms are composed of ____________ cells.

- one or more

3

Each eukaryotic organisms cell contains a clearly defined __________ enclosed by a membrane along with ___________

- nucleus
- organelles

4

Organelles

- the things or structures inside of a cell that perform the functions necessary for the cell to survive

5

Fungi are composed of ___________

- hyphae

6

Individually hypha are ___________, it elongates by ___________, and has a ___________ surface area.

- microscopic
- tip growth
- enormous

7

A mass of hyphae make up ___________

- mycelium

8

Mycelium

- a vegetative part of a fungus, or a network/mass of hyphae

9

Like plants fungi are ___________ and cannot synthesize their own food

- heterotophic

10

Heterotrophic

- can not synthesize its own food

11

Fungi are dependent on ___________ for nutrition and must secrete ___________ to absorb nutrition

- complex organic substances
- extracellular enzymes

12

To absorb nutrition fungi secrete ___________ that break down food ___________ its body into simpler compounds that the fungus can absorb and use

- enzymes
- outside

13

Fungi have a cell wall that contains ___________ and ___________

- chitin and glucans

14

Fungi are dispersed by ___________.

- spores

15

Reproductive structure of fungi is adapted for dispersion by:

1. Air currents, water droplets or foraging by small animals

2. Short lived (clear, thin walled) or long loved (dark, thick walled)

3. Sexual or asexual

16

Kingdom Fungi summary**

1. Eukaryotes
2. Composed of hyphae
3. Mass of hyphae make up mycelium
4. Heterotrophs
5. Absorptive nutrition
6. Structural components of cell wall: glucans and chitin
7. Dispersed by spores

17

Basic mushroom growth cycle

1. Stipe/stalk and cap
2. Gills
3. Spore germination
4. Hyphae fusion
5. Button formation
6. Spore production

18

Above ground, a mushroom consists of a ___________ that supports the cap

- stipe/stalk

19

The undersides of most caps have thin sheets of tissue called ___________. They contain basidia that produce ___________. ___________ disperses mature spores.

- gills
- basidiospores
- wind

20

When a basidiospore germinates, it produces ___________ of either mating strain + or -

- hyphae

21

When different hyphae meet, they fuse and form a new ___________ containing cells with ___________ nuclei

- mycelium
- 2 haploid

22

The mycelium forms a compact mass, a ___________, just below the soils surface.

- button

23

A button develops into a ___________ and ___________

- stipe/stalk
- cap

24

In the ___________ haploid nuclei fuse. Meiosis occurs producing ___________ that develop into ___________

- basidia
- four haploid nuclei
- basidiospores

25

Asexual fungi

- fungi that do not need to combine with another fungus to reproduce
- they grow and reproduce quickly

26

Hyphae

- the basic cellular unit in filamentous fungi

27

Molds and mildews

- fungi that you do not want (like weeds to plants), typically asexual
