Fungi

Question 1

autotroph vs heterotroph

Answer 1

producers/consumers

can make their own stuff. vs cant so need to ingest other organisms

Question 2

photoautotroph

Answer 2

uses sun and Co2

Question 3

chemoautotroph

Answer 3

uses oxidation of inorganic compounds as energy source, Co2 sole carbon source

Question 4

photoheterotroph

Answer 4

uses light as energy, but not Co2 as only carbon source

Question 5

chemoheterotroph

Answer 5

oxidises organic compounds as energy source

Question 6

mixotroph

Answer 6

combination of photosynthetic and heterotrophic nutrition

Question 7

genetic relationship between animals fungi and plants?

Answer 7

animal and fungi closest

Question 8

ancestor of fungi?

Answer 8

single celled aquatic flagelatted protist

Question 9

are fungi terrestrial or aquatic?

Answer 9

both

Question 10

what are fungi cell walls made of

Answer 10

chitin

Question 11

mode of energy consumption of fungi?

Answer 11

chemoheterotrophs?

Question 12

fungi contain no

Answer 12

plastids

Question 13

examples of unicellular and multicellular fungi?

Answer 13

yeast

hyphae

Question 14

describe hyphae

Answer 14

• filaments
• cell wall outside pm and organelles…
• septa separate cells, but have pore
• entire structure called mycelium

Question 15

example of specialised hyphae?

Answer 15

mycorrhizae

Question 16

describe mychorrhizae

Answer 16

-type of hyphae that go into plant cells. can be ectomychorrhizae or arbuscular.

Question 17

why is mychorrhizae/plant relationship symbiotic?

Answer 17

fungi gains carbs

plant loses phosphate and has lots of surface area for nutrient exchange

Question 18

some ecological roles of fungi?

Answer 18

• mychorrizae: symbiotic; fruiting bodies can be eaten by animals
• hyphae enable exchange of sugar between different plants
• decomposers

Question 19

describe asexual reproduciton of mycelium

Answer 19

forms spores which germinate which forms mycelium again

Question 20

describe sexual reproduction of mycelium

Answer 20

plasmogamy (cytoplasm fuse)
heterokaryotic stage (2 diff nuclei)
karyogamy (nuclei fuse) forms diploid.
meiosis occurs, forming spores
spores germinate
forms mycelium

Question 21

2 opportunistic pathogens?

Answer 21

candida ___

ringworm

Question 22

describe ringworm

Answer 22

skin infection - dematophytosis, athletes foot, tinea

Question 23

describe candidiasis

Answer 23

thrush

caused by candida

Question 24

describe candida auris

Answer 24

emerging pathgoen

• prevalent in healthcare settings
• difficult to identify with standard lab techniques
• often multi drug resistant
