Coleoid Cephalopod

The arterial and venous components of the blood vascular system of the coleoid cephalopod Illex illecebrosus were infiltrated with a vinyl plastic resin solution. This method of preparation of the vascular system provided permanent casts of its various regions. Such models greatly facilitate comparative studies of vascular architecture.

Multicellular green algae may be an ancestral form of the vascular plants. These algae exhibit cell wall structure, chlorophyll pigmentation, and physiological processes similar to those of higher plants. The presence of a vascular system which provides water, minerals, and nutrients to remote tissues in higher plants was believed unnecessary for the algae. Among the green algae, the Chaetophorales are complex highly branched forms that might require some means of nutrient transport. The Chaetophorales do possess apical meristematic groups of cells that have growth orientations suggestive of stem and root positions. Branches of Chaetophora incressata were examined by the scanning electron microscope (SEM) for ultrastructural evidence of pro-vascular transport.
