Chapter 24 Flashcards
def of Fungi
eukaryotic singles cells or vast networks of filaments that are important decompsers
Importance of fungi
Release nutrients from dead plants and animals
Trnasfer nutrients to live organisms
Great influence on biodiversity
critical to carbon cycle
Saprophytic fungi
Causes spoiling of fruits and vegetables
Decompose plant matter
How do fungi influence BIodiversity and productivity
Because they are very key to carbon cycle and nutrient cycling
Why does recycling matter?
Because if we don’t recycle, nutrients can be locked away forever without being re-introduced
Saprobes/saprophytes
Fungi that digest dead plants
Carbon cycle in the land
- Fixation by plants
- Release of CO2 by respiration
- Dead plants that have Carbon locked are used by fungi and they release CO2 by respiration
Good and bAd fungi
Good: Carbon cycle, recycling nutrients, antibiotics, and food products
Bad: Plant and animal diseases
Single called vs multicellular
Single called is called yeast
But they act the same as decomposers
Mycellium
Multicellular, grows towards food and leaves a filament skeleton
Hyphae
Long narrow branches of filament
Septa
Cross-walls espérate filaments into cells
Coenocytic
cell with multiple nuclei
Mycelia likes
- High SA/V
- Moisture
- Prone to desiccation (spores are resitant)
Mycorrhizal
SYmbiotic relationship between fungi and plant roots
