| Question | Answer |
|---|---|
| Animals | Heterotrophs by ingestion. Eat food and digest it inside their bodies. |
| Fungi | Heterotrophs by absorption, Release digestive enzymes into the environment .Break down organic material outside their bodies |
| Hyphae | long thin strands of cells that grow through soil |
| Mycelium | multicellular, a mass/network of hyphae working together. |
| Hyphae has two forms | Septate and Coenocytic |
| Septate | have septa , and one or more nuclei |
| Coenocytic | no septa, hyphae form one continues nuclei ,they are not divided into separate cells |
| Fungi can reproduce by | spores by sexual or asexual reproduction that are resistant to drying |
| Swimming Gametes and spores | primarily in water or wet soils, the gametes produced during sexual reproduction have flagella, as do the spores produced during asexual reproduction |
| Zygosporangia | haploid hyphae from two individuals meet and become joined |
| zygosporangium | Cells from yoked hyphae fuse to form a distinctive spore-producing structure |
| Basidia | Mushrooms, brackets, and puffballs form specialized club-shaped cells at the ends of hypha |
| Basidia produces 4 spores via | meiosis |
| Asci | sac like cells where meiosis and one round of mitosis produced 8 spores |
| Chytrids | aquatic and common in freshwater environments |
| What is the point of a chytrid | important decomposers, digest cellulose |
| Growth forms in Fungi | Yeasts and Mycelia |
| Zygomycetes | form a thick cell wall, live in soil, asexual reproduction is common |
| Ectomycorrhizal Fungi (EMF) | Fungi whose hyphae form a dense network that covers their host plant's roots but do not enter the root cells. |
| How does EMF go into a plant | hyphae drills between cell in the outer layer of the root |
| What does the E,F do | releases peptidases that cut of amino acids in dead tissue |
| Arbuscular Mycorrhizal Fungi | Fungi from the Glomeromycota lineage whose hyphae enter the root cells of their host plants. |
| How does AMF go into a plant | grow into root tissue while going into the cell membrane |
| Septum | any wall like structure that divide the hyphae of mycelia into cell like compartments |
| Karyotemy | fusion of two haploid nucelli into a diploid nucleus |
| Saprophyte | fungi's that feed directly of dead plant material |
| Endophyte | a fungus that lives inside of the tissues of a plant cell |
| Mycorrhizal | A fungi that lives symbiotically with the roots of vascular drives |
