Porphyra Morphology


    Porphyra blade morphology

    This alga attaches itself to the rocks by multicellular rhizoidal attachments, usually disc-shaped. The thalli begins life as uniseriate filaments but this stage is eventually replaced by parenchymatous sheets of cells (1 to 2 cells thick). This is a result of intercalary cell divison or apical division.
