Primary endosymbiois
Eukaryotic cell engulf a prokaryotic cell
Secondary Endosymbiosis
When a eukaryotic cell engulf a eukaryotic cell
Stramenopila
Straw like hairs
Where is the secondary plastids derived from

Where does mycelia grow
The mushroom edge
The mushrooms reporductive cells
Spores
Asexual spores are called

Main decomposed of cellulose
Fungi
Ascomycota (sac fungi)
Yeast (single cell) and mold
What happens without fungi
The carbon cycle would fail and carbon would be buried instead
Where are facultative or obligatory parasites
Commonly found on plant and insect host
