cyanobacteria structure

Each cell whether in a unicellular form like Gleocapsa or multicellular form like Nostoc, has a definite cell wall. Most often it is surrounded by a thin or thick mucilagenous sheath. The inner layer of cell wall has a chemical composition similar to bacterial cell, made up of peptidoglycans. The c..

There are two basic types of cells found in living organisms - the prokaryotic cells and the eukaryotic cells. This classification is based on three main features, namely; Organisation of biomembranes Nature of cytoplasmic organelles and Arrangement of the nuclear material The prokaryotic cells do ..

All plants whether autotrophic or heterotrophic require mineral nutrition for growth and metabolism. The parasitic plant, cuscuta has haustoria to derive nourishment from the host plant. A plant needs many essential nutrients for a healthy growth. They could be macro elements (required in l..

. Cyanobacteria are characterised by the presence of phycocyanin (blue) and chlorophyll (green) pigments. The Kingdom Protista includes primitive unicellular eukaryotic organisms. Protista are mainly represented by unicellular algae (such as diatoms) and protozoans - rhizopods, flagellate..
