Round, green chloroplasts in plant cells of anacharis or waterweed, Egeria densa. Chloroplasts carry chlorophyll which makes them green. These chlorplasts actually circulate around within each cell. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.
