Fungis

Question 1

The kingdom fungi belongs to what domain?

Answer 1

Eukarya

Question 2

Fungal cells have…?

Answer 2

membrane bound nucleus, mitochondria, complex internal membranes, no chloroplasts, and cell walls.

Question 3

How are fungal cells different than plant cells?

Answer 3

Plasma membranes are stabilized by ergosterol (steroid) and cell walls are made from complex polysaccharides chitin and glucan and not cellulose.

Question 4

Thallus

Answer 4

The vegetative body of a fungus

Question 5

Some fungi are dimorphic…

Answer 5

they can go from being unicellular to multicellular depending on environmental conditions.

Question 6

Yeasts

Answer 6

unicellular fungi

Question 7

What are a fungi’s two morphological stages?

Answer 7

Vegetative and reproductive

Question 8

Hypha

Answer 8

a fungal filament composed of one or more cells

Question 9

Mycelium

Answer 9

a mass of fungal hyphae

Question 10

Septum

Answer 10

the cell wall division between hyphae

Question 11

Molds

Answer 11

a tangle of visible mycelia with a fuzzy appearance

Question 12

Most fungi are obligate aerobes, which is…?

Answer 12

requiring oxygen to grow

Question 13

Some are obligate anaerobes, which means…?

Answer 13

they cannot grow in an oxygen rich environment

Question 14

Fungi can reproduce…?

Answer 14

sexually or asexually

Question 15

Like animals, fungi are

Answer 15

heterotrophs

Question 16

How do fungi digest nutrients?

Answer 16

first, exoenzymes break down environmental nutrients; then smaller molecules are absorbed through the large surface areas of the mycelium.

Question 17

What are the four major divisions of the Fungi kingdom?

Answer 17

Chytridiomycota (chytrids), the Zygomycota (conjugated fungi), the Ascomycota (sac fungi), and the Basidiomycota (club fungi).

Question 18

Glomeromycota

Answer 18

a group of fungi that form symbiotic relationships with the roots of trees

Question 19

Ascomycota

Answer 19

(sac fungi) a division of fungi that store spores in a sac called ascus

Question 20

basidiomycota

Answer 20

(club fungi) a division of fungi that produce club shaped structures, basidia, which contain spores

Question 21

Chytridiomycota

Answer 21

(chytrids) a primitive division of fungi that live in water and produce gametes with flagella

Question 22

Zygomycota

Answer 22

(conjugated fungi) the division of fungi that form a zygote contained in a zygospore

Question 23

Mycoses

Answer 23

a fungal infection

Question 24

Mycorrhiza

Answer 24

a mutualistic association between fungi and vascular plant roots (fungi gives plant water and nutrients, plant fuels fungi metabolism with byproducts of photosynthesis)

Question 25

Lichens

Answer 25

the close association of a fungus with a photosynthetic alga or bacterium that benefits both partners
