What is the study of fungi
Mycology
What type of cells are fungi
Eukaryotic

What categories can fungi be
Parasites
Saprophytes
What are parasites
Absorb food from live host
What are saprophytes
Absorb food from dead matter
Where do parasites usually get their food
Plant source
What is a obligate parasite
Can only take food from a live host
What is a facultative parasite
Can get food from live or dead host

What do harmful fungi effect
Intestine and liver
What do rhizopus consist if
Hyphae
What is a mass of hyphae called
Mycelium
What do hyphae do
Digest and absorb the substrate it grows on
What is an aerial hyphae
Stolon
What are rhizoids
Hyphae that grow into substrate
How does asexual reproduction occur in fungi
Hyphae grow up from substrate and are called sporangiophores.
Their tip swells to created sporangium who’s content divide by mitosis o form numerous spores. And spread out
How does sexual reproduction occur in fungi
Tow separate strains plus and minus grow close together.
Swellings form on each
Swellings touch
Nuclei Kobe into each swelling forming progametangia.
Walls between gametangia dissolve
Black zygospores form around nuclei
When conditions are suitable zygospores germinate by meiosis
Hyphae grow out of zygospores and product sporangium with produce new hyphae.
What are yeast
Single celled fungi
What shape are yeast
Round or oval
What are yeast cells made from
Chitinand a dense cytoplasm which contain many food vacuoles.
Are yeast aerobic or anaerobic
Anaerobic
What do yeast produce
Carbon dioxide and ethanol
How do yeast reproduce
Budding
Asexually
Mitosis
Benefits of yeast
Produce alcohol
Food source
Disadvantages of yeast
Destroy a wide range of materials Food Crops Paper Timber
