About the Image

Transverse view showing internal structure of a plasmodesma of the charophycean green alga Chara zeylanica. Digital false color computer-enhanced image from a tramission electron micrograph. A central structure appears to be connected to the plasma membrane via spoke-like structures, a feature held in common with plasmodesmata of higher plants.
