| Question | Answer |
|---|---|
| Long filaments of fungal cells joined together | hyphae |
| Vegetative hyphae | part that fungi absorb nutrients through |
| aerial hyphae | produces fungal reproductive spores |
| why are fungi mainly responsible for decomposing plant material | fungi have great tolerance for low moisture conditions |
| what temp are Pathogenic dimorphic fungi yeast like at | 37 degrees C |
| Plasmogamy | union of two haploid cells |
| Karyogamy | fusion of nuclei |
| Meiosis | cell division resulting in haploid cells |
| Anamorph | produces asexual spores only |
| Deuteromycota | a classification of fungi with an unknown reproductive method |
| Ascospore | sexually formed spore formed in a sac |
| Basidiospore | sexually formed spore found on a pedestal |
| zygospore | sexually formed, thick-walled spore formed as a segment within a hypha |
| Blastospore | asexual spore |
| fungal thallus | vegetative body of a fungus, made of hyphae |
| Mycelium | vegetative, root-like underground network of fungal hyphae |
| Coenocytic | lacking cross walls |
| Septate | with cross walls |
| Aerial mycelium | hyphae that grow above the ground |
| how do algae produce oxygen | hydrolysis of water |
| nontoxic algae | green algae |
| protozoa cyst | resilient life stage for surviving harsh environmental conditions or the journey between hosts |
| organism that can grow photoautotrophically in the light and chemoheterotrophically in the dark | Euglena |
| definitive host for Plasmodium | The Anopheles mosquito |
| when are Plasmodial gametocytes are present in the blood | at night |
| gametocytes | sexual precursor cells of Plasmodium parasites |
| helminths | worms, mostly parasitic |
| main transmission route of helminth infections | Gastrointestinal route |
| platyhelminths | flatworms |
| Cercariae | free-swimming, tadpole-like larval stage of trematode parasites (flukes) |
| Trematodes | class of flatworm flukes that are obligate parasites with at least two hosts |
| Nematodes | roundworms |
| Sporozoans | nonmotile parasitic protozoans with both sexual and asexual reproduction, often switching between hosts |
| Sarcodina | amoeboid protozoa |
| Cercariae, metacercaria, miracidia, and rediae | stages in the lifecycles of Trematodes |
| Redia | larval stage of trematodes, immediately precedes the adult stage |
| encysted larva of the beef tapeworm | Metacercaria |
| Bacteriophages and animal viruses are most similar in performing what | Adsorption |
| viral adsorption | occurs when a virus' surface element (virus attachment protein, VAP) interacts with a cellular receptor |
| The incorporation of phage DNA into bacterial host cell DNA | Lysogeny |
| prophage | phage DNA integrated into the bacterial chromosome |
| Lysogeny | when viral genome integrates into the host bacterium's chromosome |
| Cold sores | latent infection from herpes simplex virus |
| Generalized transduction | bacteriophages mistakenly package random fragments of host bacterial DNA instead of viral DNA |
| latent viruses | don't cause symptoms or cause hard to notice symptoms |
| what do latent viruses present in cells as | Proviruses |
| what do tapeworms eat | intestinal contents |
| what do hookworms eat | host tissues |
| parasitic reservoir | a host that can forever carry parasites without dying from them |
| Ringworm is caused by a(n) | Ascomycete |
| Yeast infections are caused by | Candida albicans |
