Verified
Structural elements in Kingdom Fungi - ✔✔1. Mycelium
2. Hyphae
3. Septa
4. Chitin
5. Spores
Mycelium - ✔✔-The feeding network of a fungus.
-Composed of a woven mesh of hyphae
Hyphae - ✔✔-The threadlike filaments of a fungus.
-Have a tubular cell wall that contains chitin surrounding a plasma membrane and cytoplasm
Chitin - ✔✔A structural polysaccharide of modified sugars
Coenocytic Fungi - ✔✔Are no separate cells and and many nuclei are in a common cytoplasm
Dikaryotic Fungi - ✔✔Nuclei are partitioned into 2s by septa (di-2)
Septa - ✔✔Structures that partially separate the cytoplasm inside the hyphae
The general life cycle of fungi includes the production of . - ✔✔spores
Spores - ✔✔-Haploid cells
-Grow directly into hyphae
, How many fungal species are identified - ✔✔Over 100,000
5 major divisions of fungi - ✔✔1. Chytrids
2. Zygote fungi
3. Mycorrhizae fungi
4. Club fungi
5. Sac fungi
Chytrids - ✔✔-Aquatic life cycle
-No septa present
-Characterized by swimming flagellated spores and flagellated gametes
-Some species are parasitic to amphibians
Zygote fungi - ✔✔-Zygospore
-Usually asexual reproduction, involving haploid spores that grow into sporangia
-No septa
-ex: Black bread mold and dung fungus
Mycorrhizae fungi - ✔✔-Live in intimate contact with the roots of plants
-No septa
-Hyphae surround and penetrate root cells
-Interaction forms a beneficial relationship called a mycorrhiza
Club fungi - ✔✔-Named for the basidia ("club" shaped reproductive structure)
-Usually reproduce sexually
-Septa
-The mycelium grows very large and makes fairy rings
-Ex: common mushrooms and relatives, shelf fungi, puffballs, rusts and smuts
