The plant body breaks into several parts or fragments and each such fragment develops into an individual this type of vegetative reproduction is commonly met within filamentous forms, eg, ulothrix, spirogyra, etc the fragmentation of colonies also takes place in several blue green algae, eg, aphanocapsa, aphanothece, nostoc, etc. Cell structure of green algae the cell structure is eukaryotic the cell wall generally has cellulose as the main structural polysaccharide the protoplast is bounded by a thin semipermeable plasma membrane the cells of the green algae have mitochondria, golgi bodies, ribosomes, er, plastids and other cell organelles the main pigments of.
