Fungi Flashcards
(36 cards)
What are the characteristics of a Fungi
- Eukaryotic
- Non-motile (Does not move)
- Heterotrophs (Feed off others) (Like animalia)
- Unicellular/Multicellular: Except one celled yeasts
- Cell wall (Like plants) : From Chitin
- Store Energy: Glycogen
The body of a Fungi is composed of…
Hyphae (thread-like)
A Group of Hyphae is…
Mycellium
Does the structure of a fungi contain One or Multiple nuclei
Multiple Nuclei
What are the 2 types of Hyphae
- Coenocytics: Without Septate
- Acoenocytics: With Septate
How do Fungi’s get their Nutrition
They undergo external digestion and secrete digestive enzymes then consuming them
Are Fungi’s Heterotroph or Autotroph
Heterotroph, they absorb digested material into cell.
- Predators: Paralyzing Prey
- Parasites: Feeding on living creature
- Decomposers: Breakdown dead remains
What does a fungi use to get their food
They use a structure called Hyphae.
(Except for yeast which are unicellular)
(Hyphae: threadlike tubes. Shape of fungi depends on how hyphae is used)
How does the hyphae absorb their food
The fungus grows hyphae into food then hyphae secrete digestive chemicals into food. After food is broken down then the hyphae absorbs it
In the general structure of a Fungi what are the 3 things
- Stem-like Hyphae
- Root-like Hyphae (Rhizoid)
- Reproductive-like Hyphae
In the ecological role and symbiotic relationship. What is a lichen a combination of
fungi + algae
How does the symbiotic relationship in a Lichen work
The fungi delivers water and mineral to algae
And the algae will use its photosynthesis to provide sugars for fungi
What is meant by Pioneer Species in lichen
If the ecosystem they are in is destroyed because they have the symbiotic relationship they are able to live in extreme condition and become the first and founder of the ecosystem due to its ability to survive under harsh conditions
In the ecological role and symbiotic relationship. What is a Mycorrhizae a combination of
Fungi + Plant
How does the symbiotic relationship in a Mycorrhizae work
Enables plants to absorb more water
What are plants with fungi called and without fungi called
Plant with fungi: Ectomycorrhiza
Plant without fungi: Endomycorrhiza
What are the asexual reproduction in fungi
- Budding (Yeast only because unicellular)
- Fragmentation
- Asexual Spores
What is the sexual reproduction in fungi
Spores: Spread by wind
How does spores in reproduction work
-Produce thousands of spores with a protective covering: carried by water and air
-Spores land in a warm, moist place to grow
-When there are plenty of moisture, fungi reproduce asexually by releasing the spores
-When conditions are not good they reproduce sexually making new spores that are different from both parents
Fungi are divided based on its…
Sexual Spores
What are the types of Fungi
- Zygomycota
- Ascomycota
- Basidiomycota
- Deuteromycota
What are the characteristics of Zygomycota
- Coenocytic Fungi
- Sexual Spores: Zygospores
- Asexual Spores: Sporangiospores
- Mostly in soil and decompose dead matters
- Some useful, some parasites
The structure of a Zygomycota has 5 things which are
- Sporangiospores
- Sporangium (box of sexual spores)
- Sporangiophore
- Rhizoid
- Generative Hyphae (+/-)
What are the examples of Zygomycota and what is its role
- Mucor Mucedo: Saprobes on animal feces
- Mucor Javanicus: Fermented sticky rice and cassava
- Rhizopus Oryzae: Tempe, Sake, and Wine
- Chlomydomucor Oryzae: Tempe
- Rhizopus Nigricans: Spoiling Bread
