|
Definition
| A eukaryote(with nuclear membranes and organelles). Larger than a bacteria |
|
|
Term

|
Definition
| Present. Contains ergosterol. No chlorophyll. |
|
|
Term
|
Definition
| A sexually. A defining characteristic of fungi that allows for differentiation among different fungi |
|
|
Term
| Do they have similar biochemical pathways to other kingdoms? |
|
Definition
| Biochemical pathways are very different, indicating that the fungi branched from the tree of life fairly early in evolution. |
|
|
Term
| Classification of Fungi - what makes it difficult? |
|
Definition
| Growth is variable in different conditions. |
|
|
Term
| Classification of Fungi - best method? |
|
Definition
| based on structures formed during sexual reproduction. |
|
|
Term
| Human pathogens - sexual structures? |
|
Definition
| Many do not form sexual structure and so belong to a class called deutermycetes. |

|
Term
| Classification of Fungus - convenient method? |
|
Definition
|
|
Term
|
Definition
| Single celled organism. Some elongate to form chains of cells called pseudohyphae. |
|
|
Term
|
Definition
| Reproduce by budding to form daughter cells or blastospores. Some are commensal(benefits from the host but does not cause harm). |
|
|
Term
| Moulds appearance? Structure? |
|
Definition
Multicellular, form tubular structures called hyphae which may have cross walls (septate) or lack cross walls (aseptate).
Many hyphae form a mycelium. |
|
|
Term
|
Definition
| Specialized structures produce asexual spores. |
|
|
Term
| arthrospores? What are they? |
|
Definition
| Some hyphae fragment (septate) to form spores. |
|
|
Term
| Dimorphic fungi - what are they? Where do they exist? What are there different forms? |
|
Definition
Fungi that behave as both yeasts and moulds.
Grow as moulds at room temperature producing spores which are infectious.
Grow as yeast at elevated temperatures(body temperature).
Geographically limited in distribution. |
