Achlorophyllous Rhizoids which are important for
Anchorage & Absorption are also produced early in Germination.

There are three
Types of Protomena

Type 1 Protonema continues as
Photosynthetic  Chloronema

Type 2 Protonema grows into the Soil to form "Rhizomes" (?Rhizonema?)

Type 3 Protonema forms many
Leafy Shoots & is known as Caulonema

Gameto = Gametangia
phore = Hold
