Unit 4

Question 1

Are fungi prokaryotic or eukaryotic and what group do that relate most closely to?

Answer 1

Eukaryotes that relate most closely to animals

Question 2

Explain how DNA is organized in Fungi

Answer 2

Because fungi are Eukaryotic their DNA is arranged in multiple linear chromosomes

Question 3

Are Fungi unicellular or multicellular

Answer 3

Multicellular (with some exceptions)

• yeast is unicellular Fungi

Question 4

The vegetative body of a fungi is called the ___________ and is composed of many intertwined ____________

Answer 4

Mycelium, hyphae

Question 5

Describe the cell wall in Fungi

Answer 5

The cell wall is porous, composed of chitin and consists of many layers of microfibrils.

Question 6

Describe fungal digestion

Answer 6

Digestion is extracellular; Digestive components are released into the environment to break down nutrients and then those nutrients are absorbed through the hyphae.

Question 7

Do terrestrial Fungi have motile or non motile reproductive cells

Answer 7

Non motile

Question 8

Do Fungi reproduce asexually or sexually

Answer 8

Fungi reproduce both sexually and asexually

Asexual reproduction- no genetic recombination and results from mitospores

Sexual reproduction- genetic recombination results from syngamy and meiosis

Question 9

Are members of Chytridiomycota terrestrial or aquatic

Answer 9

Primarily aquatic

Question 10

What is the energy storage reserve of Chytrids (Chytridiomycota)

Answer 10

Glycogen

Question 11

Members belonging to what fungal group have motile (flagellated) sperm; usually posteriorly inserted whiplash flagellum

Answer 11

Chytridiomycota

Question 12

This type of flagella are smooth

Answer 12

Whiplash flagellum

Question 13

This type of flagellum is hair-like

Answer 13

Tinsel flagellum

Question 14

A spore that can move (swim) due to having flagella

Answer 14

Zoospore

Question 15

How do Fungi get their carbon and energy sources

Answer 15

They are chemoheterotrophic

Question 16

Bread molds are representatives of which fungal group

Answer 16

Zygomycetes

Question 17

List the three types of Lichen morphology

Answer 17

Fruiticose - tubular
Folios - flattened
Crustose - grows in something

Question 18

What three fungal groups have non motile (non flagellated) spores

Answer 18

Zygomycetes (bread molds)
Ascomycota (yeasts)
Basidiomycota (club fungi)

Question 19

Describe the hyphae in chytrids

Answer 19

Coenocytic (not cellular/multinucleate) with septa few or absent

Question 20

Describe the hyphae in Zygomycetes (Zygomycota)

Answer 20

Generally coenocytic (noncellular/multinucleate) with septa few or absent

Question 21

Describe the hyphae in Ascomycetes (Ascomycota)

Answer 21

The hyphae are separate with perforations

Question 22

Describe the hyphae in Basidiomycetes (Basidiomycota)

Answer 22

They hyphae are separate with perforations

Question 23

They study of fungi

Answer 23

Mycology
