Answer 2

Hetertropic
Saprophytic - dead sources
Parasitic - living sources

Question 3

Answer 3

Field mushroom
Truffle

Question 4

Answer 4

Death cap
Destroying Angel

Question 5

Economic benefits of fungi

Answer 5

Penicillin
Yeast

Question 6

Economic downsides to fungi

Answer 6

Destruction of crops
Human disease

Question 7

Rhizopus nutrition

Answer 7

Saprophytic
Feeds on starchy foods eg. Bread

Question 8

Rhizopus structure - Spore

Answer 8

tiny reproductive cell that can grow into a new Rhizopus fungus

Question 9

Rhizopus structure - Sporangium

Answer 9

Round structure that produces and releases spores

Question 10

Rhizopus structure - Apophysis

Answer 10

slight swelling at the base of the sporangium that supports it.

Question 11

Rhizopus structure - Collumella

Answer 11

dome-shaped structure inside the sporangium that helps distribute spores

Question 12

Rhizopus structure - Sporangiophore

Answer 12

stalk that holds up the sporangium

Question 13

Rhizopus structure - Stolon

Answer 13

Horizontal hypha that spreads across the surface of the substrate

Question 14

Rhizopus structure - Hypha

Answer 14

A single thread-like strand of fungal cells

Question 15

Rhizopus structure - Mycelium

Answer 15

The network of hyphae that makes up the main body of the fungus.

Question 16

Rhizopus structure - Rhizoids

Answer 16

Root-like hyphae that anchor the fungus and absorb nutrients

Question 17

Rhizopus structure - Substrate

Answer 17

The material the fungus grows on (e.g., bread, fruit)

Question 18

Rhizopus reproduction - sporulation

Answer 18

The process of making new spores

Question 19

Rhizopus asexual reproduction

Answer 19

Ideal conditions -> Hyphae grows into sporangiophore. Sporangium at tip of sporangiophore divides by mitosis - new spores. Bad conditions -> spores release

Question 20

Rhizopus sexual reproduction - formation of progametangia

Answer 20

+ and - strains grow close + grow swellings which touch. Nuclei move into swellings forming progametangia

Question 21

Rhizopus sexual reproduction - formation of gametangia

Answer 21

Cross wall forms in the middle of gametangia then dissolves allowing for fertilisation producing several zygote diploid nuclei

Question 22

Rhizopus sexual reproduction - formation of zygospore

Answer 22

Hard black zygospore forms around nuclei, staying dormant until conditions are favourable. When conditions are favourable zygospore germinates forming haploid hyphae. Sporulation occurs

Question 23

Yeast & Rhizopus - which is unicellular and which is multicellular

Answer 23

Yeast is unicellular
Rhizopus is multicellular

Question 24

Yeast cytoplasm filled with…

Answer 24

Food vacuoles

Question 25

Yeast reproduction

Answer 25

Budding Parent cell divides by mitosis and a new "bud' separates In ideal conditions when yeast is dividing rapidly the buds may fail to separate which causes a colony to form.
