Yeast form interwoven mats known as mycelia.
The yeast form is the most common form of fungi.
Yeast forms grow as long branching filaments.
The yeast forms of fungi are unicellular.
Bacteria since this is a common form of reproduction for bacteria.
Hyphal fungi since hyphal fungi form buds when they grow on plates.
Yeast since they commonly reproduce asexually by budding.
Tiny plants just ready to produce flowers.
