The structure of the cyanobacterium (above) is composed of
the following functions:
I) Lipid droplet -spherical droplets composed of lipids and proteins that are used as a way of storing lipids
II) Nucleoid (circular DNA) – similar to a nucleus,
keeping genetic information
III) Protein Granule – grains of protein providing
protein throughout the cell
IV) Ribosome – synthesizes protein chains from amino
acid molecules
V) Photosynthetic Lamellae - a thin layer, plate, or membrane for
a stronger structure
VI) Phycobilisomes (cyanosomes) – responsible for a
result of 95% efficient energy transfer
VII) Plasma membrane – surrounds the bacteria,
controlling the movement of substances into and out of the cell
VIII) Cell wall - a structural support and protection, in addition to acting as a filtering
mechanism
IX) Gelatinous coat – an exterior fibrin gel
protecting the cell from injuries
