NURSING ANM AND GNM

Detailed explanation-1: -Cyanobacteria, formerly known as blue-green algae, are photosynthetic microscopic organisms that are technically bacteria. They were originally called blue-green algae because dense growths often turn the water green, blue-green or brownish-green.

Detailed explanation-2: -Chlorella. Chlorella is a genus belonging to the Chlorophyta group of single-celled green algae.

Detailed explanation-3: -The ancestral species in the green lineage were likely to be small unicellular marine biflagellates that originated around 1 billion years ago (De Clerck et al. 2012), and this form is still prevalent among modern aquatic algae.

Detailed explanation-4: -The name cyanobacteria refers to their color (from Ancient Greek (kuanós) ‘blue’), which similarly forms the basis of cyanobacteria’s common name, blue-green algae, although they are not usually scientifically classified as algae.

Detailed explanation-5: -Note: As cyanobacteria have chlorophyll pigment in them scattered in not well-organized thylakoids of the chloroplast, these are thought to be primitive algae. Also, it is thought that once cyanobacteria cell was associated with the plant cell and this resulted in a typical plant cell having chlorophyll.
