Characteristics of fungi
|
Fungal life cycles involve growth, phase, and reproductive phase
Molds grow in long, tangled filaments Yeast are unicellular fungi Some DIMORPHIC form Grow at filamentous molds or unicellular phatogens Most exist as HYPHAE HYPHAE is intertwined filaments of fungus MYCELIUM is thick mass of HYPHAE Fungal cell walls made of CHITIN Septa divides cytoplasm into separate cells Hyphae contain many nuclei considered coenocytic Heterotrophic Absorbs nutrients from environment Saprobes |
|
|
Fungal Growth is influenced by several factors
|
Take up nutrients through absorption
MYCELIUM form networks to increases surface area Most are aerobic Grow best around room temperature Many thrive at slightly acidic pH (5-6) Mycorrhizae live in mutualistic symbiosis w/ plant roots endophytes live in plant tissue, particularly leaves |
