LM of blue-green algae,Spirulina major
Numéro d’image : 11998136
| Spirulina algae. Light micrograph,using phase contrast,of rows of unicellular blue-green algae,Spirulina major. Blue-green algae (cyanobacteria) are primitive algae,producing their food from sunlight using photosynthesis. Their internal structure is closely related to bacteria. They are prokaryotic organisms which contain no membrane-bound nucleus; instead,as in bacteria,their nuclear material is dispersed throughout the cell. Some Spirulina species are eaten as a protein-rich health food. Phase contrast images reduce the colour saturation of objects,allowing greater detail to be seen. Magnification: x25 at 35mm size | |
