Fungi are known as ? What are they? |
Known as "fun guys." They are eukaryotes. |
|
Fungi is classified as ? |
Are chemoheterotrophs---use chemicals to get energy &carbon |
|
How does fungi acquire carbon? |
Through nutrient absorption. |
|
Are fungi multicellular? |
Fungi is multicellular except for yeast. Yeast is unicellular. |
|
How can fungi reproduce? |
Asexually- make Asexual spores & Sexually - make sexual spores |
|
What is the study of mycology? |
Study of fungi |
|
CHARACTERISTICS OF FUNGI COMPARED TO BACTERIA---characteristic cell type |
Fungi are eukaryotes Bacteria are PROkaryotes |
|
CHARACTERISTICS OF FUNGI COMPARED TO BACTERIA---characteristic cell wall: |
Fungi cell wall made of chitin Bacteria cell wall made of peptidoglycan |
|
CHARACTERISTICS OF FUNGI COMPARED TO BACTERIA---characteristic- spores: |
Fungi produce spores for reproduction. Bacteria produce spores for survival. |
|
CHARACTERISTICS OF FUNGI COMPARED TO BACTERIA---characteristic-motility |
Fungi are NOT motile, can travel through air. Bacteria are motile - have different structures for motility. |
|
CHARACTERISTICS OF FUNGI COMPARED TO BACTERIA---characteristic--reproduction: |
Fungi reproduce sexual and Asexually-. Bacteria reproduce Asexually. |
|
CHARACTERISTICS OF FUNGI COMPARED TO BACTERIA---characteristic--# of cells-- how many cells are they made up of? |
Fungi are multicellular except yeast. Yeast is unicellular. Bacteria are made of 1 cell--- unicellular. |
|
What type of fungi is multicellular? |
Molds |
|
What does mold have? |
It has a thallus-body Hyphae- long filamentous structures made up of multiple cells. |
|
What organism contains septate hyphae? What is septate hyphae? What is the picture of? |
Molds Septate hyphae -long filamentous structures made up of multiple cells that have a nucleus and separated by a wall.
This septate hyphae have a cross wall that separate the nuclei. Picture is Aspergillus--septate hyphae. |
|
What organism has coenocytic hyphae/ Aseptate hyphae? What is it? What is this picture of? |
Molds contain this coenocytic hyphae/ Aseptate hyphae. It does not have a cross wall to separate the nuclei. Picture is Rhizopus--aseptate hyphae |
|
Where does the hyphae come from? |
Hyphae germinates from a spore. Spores can produce different hyphae. |
|
Since hyphae germinates from spores... What are the types of hyphae they produce? |
Vegetative hyphae Arial hyphae |
|
What is the function of vegetative hyphae? |
It's a hyphae in mold that's involved in the absorption of nutrients. |
|
What is the function of aerial hyphae? It's also known as? |
Aerial hyphae is also known as reproductive hyphae. Involved in reproduction that holds the spores at the end of the hyphae. |
|
The hyphae that is attached to the spores is? |
Aerial/reproductive hyphae |
|
What is the hyphae that it's not attached to spores? |
The vegetative hyphae |
|
What type of organism is this? |
Rhizopus hyphae |
|
What is mycelium? |
A filamentous mass of vegetative hyphae |
|
YEAST---is made up of how many cells? Does it contain hyphae? Is it filamentous? |
Yeast unicellular Does not contain hyphae, therefore yeast is non-filamentous. |
|
Types of yeast? How does yeast divide? |
Fission yeast: divides symmetrically Budding yeast: divides a symmetrically |
|
What is this a picture of? How is it dividing? |
This is Fission yeast- dividing symmetrically |
|
What is this? How is it dividing? |
Budding yeast: divides asymmetrically |
|
Define: Pseudohyphae |
False hyphae. The budding yeast fails to detach. Thus creating a long chain. |
|
Describe each yeast division |
1. Traditional yeast 2. Pseudohyphae 3. True hyphae |
|
What type of organism is this? |
Aspergillus niger |
|
What organism is this? What is the medium? |
This is Aspergillus niger on agar media |
|
What is candida albicans? What can it cause? |
It is a yeast specifically an opportunistic pathogen. Causes infections with those who have compromised immune systems. Infections like: Yeast infections Oral thrush |
|
What type of organism is this? How does it reproduce? |
This is candida albicans. Reproduces via Asexual reproduction. "Budding"- Asymmetrically |
|
Rhizopus stolonifer---what is it? Is it Multicellular or unicellular? |
It's a mold. Known as "bread mold." It's multicellular. |
|
What kind of spores does rhizopus stolonifer have? |
Rhizopus stolonifer has both asexual and sexual spores. |
