Intro to Fungi
BIO Lab Exam 3
| Question | Answer |
|---|---|
| Almost all fungi are | multicellular heterotrophs |
| Which fungi is NOT multicellular? | Yeast is unicellular |
| What is the cell wall composed of for fungi? | Chitin |
| How does fungi digest nutrients? | Digests organic material externally and absorbs nutrients |
| What is chiton found in besides fungi? | Exoskeletons of insects, spiders, crabs, and many more |
| What pigment does fungi produce that animals also produce? | Melanin |
| How does fungi store carbohydrates, similarly to animals? | Stores as glycogen |
| What is the major different between fungi reproductive structures? | The production of spores and the type of spore that is produced |
| What type of ancestor did fungi evolve from? | A unicellular heterotrophic protist |
| What are fungi composed of? | Hyphae, microscopic filamentous branching cells |
| What does the hyphae make up? | The mycelium |
| Where does the mycelia grow? | In the medium of the fungi |
| How does the fungus feed? | By external digestion and absoprtion |
| What does the nuclei do in some fungi? | Moves freely in the hypha |
| Coenocyctic | Multi-nucleate |
| In most fungi, what is the nuclei separated by? | In the hypha there separation is by the septa |
| What are mutualistic fungi called? | Mycorrhizae |
| How does the fungal life begin? | A spore |
| What is a spore? | A haploid |
| What does the haploids do sometimes? | Divide by mitosis (asexually) into multicellular n (haploid) form |
| Which sexual reproductive alternation does fungi go between? | Asexual and sexual |
| Name for Spore-Bearing Structure | Sporangium |
| Where do some fungal hyphae grow? | In the n (haploid) state |
| Fungi asexual reproduction involves | producing spores bearing structures called sporangia |
| What does sporangia produce? | Haploid spores that disperse and grow new identical fungus |
| What are Zygomycota known as? | Zygote fungi |
| What are zygote fungi? | Bread and fruit molds |
| Coenocytic condition is | multinucleated non-separate hyphae |
