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.
Dinophysis algae under microscopic view, Chromista, diatoms, phytoplankton, fossils, silica, golden yellow algae

Aspergillus fumigatus is one of the most common Aspergillus species to cause disease in individuals with an immunodeficiency. This pathogen primarily causes invasive infection in the lung.
The small but mighty phytoplankton are the laborers of the ocean, they serve as the base of the food web
Squash preparation of  onion root tip cells stained to reveal chromosomes,  Bright field illumination, light microscopy.  This image was taken with the X40 objective lens.  Depth of focus is extremely low at this magnification.  Smaller apertures give greater depth of focus, but image quality deteriorates and resolution is greatly reduced.  The aperture in this image was optimised for contrast and resolution. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.

The algae species Pediastrum boryanum under the microscope.
Photomicrograph of Volvox globator, a green algae in various stages of development. Dark green spots are daughter colonies forming inside of parent colony. Live specimen. Wet mount, 10X objective, transmitted brightfield illumination.
