Early transmission electron micrograph showing intracisternal granules with an electron density equal to that of zymogen granules found in rough endoplasmic the reticulum lumen (cisternae) of animals ...

Transmission electron micrograph of a thin section of the liver of a 1-day old rat showing a grazing view of rough endoplasmic reticulum (RER, sometimes termed granular endoplasmic reticulum. The 'rou...

Scanning electron microscope image of cross-section through a Psidium guajava stem. The image shows the thin outer epidermal layer with a thick layer of cortex beneath. The vascular area consists of ...

Scanning electron microscope image of cross-section through Helianthus annuus (sunflower) stem. The image shows the outer epidermal layer, followed by the cortex and then large vascular bundles. The v...

Scanning electron microscope image of a longitudinal section of a Helianthus annuus (sunflower) stem showing vascular bundles. This image is part of a group on botanical stems (CIL:40378-40395).

Scanning electron microscope image of showing the phloem and xylem in a vascular bundle. This image is a high magnification view of CIL:40394. This image is also part of a group on botanical stems (C...

Scanning electron microscope image of Vibrio cholerae bacteria, which infect the digestive system. This image is part of an image group that includes CIL:40395-40399.

Transmission electron micrograph of a representative sertraline-treated arf1Δ mutant cell. ARF1 encodes a small regulatory GTPase that nucleates vesicle formation in the early secretory pathway. The...

Transmission electron micrograph of a Golgi stack from an untreated arf1∆ mutant cell. A large unbudded coated vesicle is apparent. (31,500X). This image is part of an image group of cisternae imag...

Abnormal organelles from a sac1∆ mutant treated with 60µM sertraline. This image is a high-magnification zoom of the cell in CIL 40433. This image is part of an image group of cisternae images, CI...
