Missing the beginning of the film. The film explores the structure and function of plant and animal cells using a microscope. It begins with observing onion cells, highlighting their components such ...

The sunlight-collecting organelles known as chloroplasts solve a packing problem: how to optimize photosynthesis without ...

Plant cells are surrounded by an intricately structured protective coat called the cell wall. It’s built of cellulose microfibrils intertwined with polysaccharides like hemicellulose or pectin. We ...

A new hybrid microscope for the first time allows scientists to simultaneously image the full 3D orientation and position of an ensemble of molecules, such as labeled proteins inside cells. (Nanowerk ...

Artistic rendering of cellulose biosynthesis with zoomed in view. Individual cellulose chains (dark brown) are synthesized by plasma membrane-bound (purple) cellulose synthase enzyme complexes (cream) ...

Using a tiny, spherical glass lens sandwiched between two brass plates, the 17th-century Dutch microscopist Antonie van Leeuwenhoek was the first to officially describe red blood cells and sperm cells ...

For most of their lives, plants get their energy from photosynthesis. But during the seed to seedling stage, when they can't absorb light just yet, they rely on other sources, like fatty acids. To ...
