Darkfield contrast light micrograph of a Frontonia sp. ciliate protozoan, showing the symbiotic green algae (Zoochlorellae, green) contained in vacuoles within. These protozoa use the algae to produce food for them through photosynthesis. In return the algae gain protection from their host. Magnification: x230 when printed 10 centimetres wide. | |
