Bryophytes (Mosses)

Moss gametophyte protonema branching from rhizome

Protoplast in gametophyte rhizome cell

Gametophyte protonemal bud emerging from rhizome

Rhizome slanted cell end wall, and numerous elongate chloroplasts

Diagonal cross-wall in protonema

Old branch on protonema

Numerous branching uniseriate protonemal trichomes

Numerous discoid chloroplasts in protonema are apparent.

Tangled mass of protonema (x200)

Tangled mass of protonema (x100)

Winding branches give an impression of anastomoses, though none were confirmed.

Frequently branching protonema trichomes

Protonema "network" of trichomes (x400)

Rhizome, multiple protonema trichomes, and possible later stage of gametophyte
