Bio Wk 19 Flashcards
What are the 3 Domains of Classification?
- Bacteria
- Archaea
- Eukarya
What are the 6 Kingdoms of Classification?
Including this week, we’ve covered 4 of the 6.
- Eubacteria
- Archaebacteria
- Protista
- Fungi
- Plants
- Animals
Fungi are (heterotroph / autotroph) that get
nutrients from ________ if they are free living,
or their ____ if they are parasitic.
with cell walls made out of _______ .
Fungi are (heterotroph / autotroph) that get
nutrients from decaying matter if they are free living,
or their host if they are parasitic.
with cell walls made out of chitin.
The only unicellular fungi is _______ .
The only unicellular fungi is yeast.
BONUS: What delicious things does it make for us?
Fungi that is multicellular is constructed of “stringy”
filaments called ________ that are 1 cell thick.
They form a tangled web called _________
that absorbs nutrients.
Fungi that is multicellular is constructed of “stringy”
filaments called hyphae that are 1 cell thick.
They form a tangled web called mycelium
that absorbs nutrients.
Just like slime molds,
the fungi grow a fruiting body.
What is this ?
Give an example of one you’ve seen.
The fruiting body is
the reproductive system of the fungi
that makes spores to reproduce.
HINT: You’ve seen fruiting bodies on pizza before…
There are 2 types of reproduction.
What are they?
Are the offspring clones or genetic variations?
Asexual reproduction: clones, exact genetic copies of the single parent.
Sexual reproduction: male & female join genetic material to create a genetically mixed offspring.
What are the 3 types of asexual reproduction?
What is the difference between them?
Binary fission- organism splits in 2 creating 2 organisms
Budding- organism grows a “baby” that breaks off
Fragmentation- organism fractures a piece off that can regenerate/grow into an organism.
What are sporangium?
Sporangium form at the tips of fungi hyphae
and make spores (asexual reproduction)
that are dispersed and grow into new hyphae (clones).
Fungi also sexually reproduce when hyphae grow as __ or __ , each a haploid like sperm or egg.
The 2 different hyphae grow next to each other, then fuse and share ____ where their haploid DNA is found.
The sharing of DNA between hyphae is called ____ fusion.
Fungi also sexually reproduce when hyphae grow as + or - , each a haploid like sperm or egg.
The 2 different hyphae grow next to each other, then fuse and share the nucleus where their haploid DNA is found.
The sharing of DNA between hyphae is called nuclear fusion.
In fungi sexual reproduction, after the + and - hyphae perform nuclear fusion , the ________ is formed with diploid spores (like animal zygotes).
Unlike animal zygotes that go on to grow into diploid organisms, gametangia undergo ______ (not mitosis) to split the dipoid spores into ______ spores that go on to grow into 2 types of hyphae.
In fungi sexual reproduction, after the + and - hyphae perform nuclear fusion , the gametangia is formed with diploid spores (like animal zygotes).
Unlike animal zygotes that go on to grow into diploid organisms, gametangia undergo meisois (not mitosis) to split the dipoid spores into haploid spores that go on to grow into 2 types of hyphae.
What are the 4 fungi groups?
- Common molds (the cheese touch)
- Sac fungi (sacs and cups)
- Club fungi-
- Imperfect fungi- foot grossness
- Common molds:
* Name the 2 hyphae (one spreads out, the other forms “roots” that digest)
* How does it reproduce?
- Common molds:
* Two hyphae: stolons (spread) and rhizoids (root-like)
* Reproduce: asexual haploid spores released into the air. (review gametangia slide)
- Sac Fungi: Can reproduce asexually or sexually
* Asexual: Hyphae conidiophores form +/- haploid ______ that then grow into more hyphae.
* Sexual: +/- haploid hyphae fuse permanently into gametangia but don’t form _____ right away. They then grow into the _______ we can see with our eyes.
* Asexual: Hyphae conidiophores form +/- haploid conidia that then grow into more hyphae.
* Sexual: +/- haploid hyphae fuse permanently into gametangia but don’t form diploids right away. They then grow into the fruitiing body we can see with our eyes.
Sac fungi sexual reproduction continued:
Fused +/- hyphae/gametangia remain haploids that grow into the fruiting body and form the _______ (singular = asci), that then fertilze to form the _______ zygote.
This zygote undergoes meisosis = haploid cells, then mitosis to form ________ (haploid spores formed by the ascus) that are released to grow into haploid hyphae & start the cycle over
Sac fungi sexual reproduction:
Fused +/- hyphae/gametangia remain haploids that grow into the fruiting body and form the ascus (singular = asci), that then fertilze to form the diploid zygote.
This zygote undergoes meisosis = haploid cells, then mitosis to form ascospores (haploid spores formed by the ascus) that are released to grow into haploid hyphae & start the cycle over
