Scanning electron micrograph of the epidermal surface of lamprey larvae. A row of microvilli outline the polygonal borders between cells, while short microvilli cover the external surface in a reticu...

Colorized scanning electron micrograph of rust on a rose leaf. Rose rust is a disease specific to roses and is caused by the parasitic fungus Phragmidium tuberculatum and some other closely related s...

The video shows a cytoplast that is adhering to a sub-stratum in its central portion. It is also connected by a retraction fiber to its central cell. The cytoplast is engaging in vigorous protrusive a...

The video shows epidermal cells at the edge of an epithelial sheet in culture. There is vigorous lamellipodial activity at the edge of the cell cluster. Lysosomes and elongated mitochondrial are seen ...

Electron micrograph showing fingerprint like ridges called microplicae on the surface of fish skin epidermis from the neon tetra. These ridges offer mechanical reinforcement against trauma and help ho...

Colorized scanning electron micrograph of a lavender leaf. Lavender (Lavandula) yields an essential oil with sweet overtones, and can be used in balms, salves, perfumes, cosmetics, and topical applica...

A more fully differentiated epidermal cell. The nucleus and nucleoli are on the left. The video shows the intracellular movements of lysosomes and mitochondria. The lysosomes are the small refractile ...

Upper panel shows a transmission electron micrograph featuring the nuclear envelope with the nuclear lamina seen here as a uniform layer between the inner nuclear membrane and more darkly staining blo...

Upper: capillary endothelial cell junction in the rete mirabile of the gas bladder of the toadfish Opsanus tau shows dense intracelluular plaques and the central dense line in the intercellular space,...

Rough endoplasmic reticulum and Golgi in epidermal cells of Fundulus heteroclitus scales. Epidermal cells undergoing advanced stages of scale development have prominent rough endoplasmic reticulum and...
