what is the basic shape of individual cyanobacterial cells? Contrast the arrangement of these cells
in the two different types of cyanobacteria you observed (anabaena, oscillatoria, gleocapsa are
the ones we observed)
Solution
Cyanobacteria exist in a wide varety of sizes and shapes. The most common among them are
spherical, rod and spiral. The shapes of differenent cyanobacteria are dicated by their cell
wall.Based on their shape, known more formally as their “morphology,” cyanobacteria have
been classified into five groups: chroococcales, pleurocapsales, oscillatoriales, nostocales and
stigonematales. However, the common lineage of only the last two groups has been established.
Individiual cells vary in size and shape.Most of them are slender and tubular, but some have a
more flat oval shape.
Anabaena is a filamentous cyanobacteria. However, it can be easily distinguished by the
presence of string-beaded appearance taken up by cells associated with each other. Several
intercalary heterocysts are present in the trichome.
Oscillatoria belongs to filamentous form of cyanobacteria, with more than 100 sub-species.Its
body is composed of single row of cells, with unbranched trichomes and single layer of
mucilage.
Gleocapsa forms spherical colonies, enclosed in a thick layer of mucilage..
