Cells of algae with chloroplast, Microscopic magnification
plant Pumpkin ovary under light mircoscope with white background
Illustration of animal cell anatomy
3d cell organelle - nucleus (Chromatin,  Rough Endoplasmic Reticulum, Nucleus Shell, Nucleoplasm, Nucleolus)
view of vegetal cells through a 1000x microscope lens
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.
Amphora sp. algae under microscopic view pattern, Diatoms, phytoplankton, fossils, silica, golden yellow algae
Abstract pie charts & circular charts on an engineering blueprint surface. Wide horizontal close up composition.
Host cells with spores (mold) are inside wood under the microscope for education.

Filamentous carbon has thermodynamic properties that are different from those of graphite. This is partially due to the fact that the structure of filamentous carbon is more disordered than the structure of graphite.

Structure of Escherichia Coli
Anther, in flowering plants, the part of a stamen that produces and contains pollen. Each anther is generally borne at the tip of a long slender
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.

3D Gaussian surface and cartoon models, chain id color scheme, PDB 2axt, putative membrane is shown, white background
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.
