What are the two replication methods yeasts use?
Budding
Binary fission
What are the three types of sexual reproduction structures yeasts can perform?
- Zygomycota
- Ascomycota
- Basidiomycota
What is Zygomycota
No seperation of the cell, Leading to either asexual spore release or sexual production
What are Ascomycotas?
Asco’s are produced, which results in production of conidia
What are asco’s?
Sacks of spores
What are Basidiomycota
Seperate hyphae which sexually reproduce through basidium
How do the Mycorrhizia assist plants?
They wrap around the roots, assisting with water absortption and nutrient uptake
What moulds are most commonly linked to food spoilage?
Aspergillus and penicillum
