Golgi apparatus of eukaryotic cells functions in protein synthesis. I loved my molecular biology class and love this photo. Now, how to incorporate cell structure and cellular functions for my class?

Synapse in Brain    Deep inside the brain, a neuron prepares to transmit a signal to its target. To capture that expectant, fleeting moment with painstaking detail, science illustrator Graham Johnson based his elegant, highly accurate drawing on ultra-thin micrographs of sequential brain slices. The brain contains billions of neurons, whose network of chemical messages form the basis of all thought, movement and behavior. Johnson's illustration tells the story of one such millisecond signal.

A clinical trial of an Alzheimer’s disease treatment developed at MIT has found that the nutrient cocktail can improve memory in patients with early Alzheimer’s.

A dense network of blood vessels in the alveoli enables the quick transfer of oxygen to the bloodstream in the lungs. Here blood cells can be seen squeezing through the narrow capillaries. Taken by professional science photographer Oliver Meckes, the image won second prize in the competition.

Phagocytosis. Coloured scanning electron micrograph of a polymorphonuclear white blood cell or leucocyte, attacking Bacillus cereus bacteria. The leucocyte (orange), part of the body's immune system, is attaching to and engulfing the Bacillus cells (blue, rod- shaped). It uses enzymes to digest the bacteria. This process of engulfment and digestion is known as phagocytosis. Highly mobile, phagocytic cells migrate to areas of tissue damage.

DNA Ligase, an enzyme that repairs DNA damage ru.wikipedia.org

Repairing DNA - Like a watch wrapped around a wrist, a special enzyme encircles the double helix to repair a broken strand of DNA. Without molecules that can mend such breaks, cells can malfunction, die, or become cancerous.
