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

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 ...

Before seedlings can photosynthesize, they depend on fatty acids—and on peroxisomes to process them. Researchers discovered that the protein PEX11 not only helps these structures divide but also ...

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) ...

Explore 25 astonishing things you can only see under a microscope. Discover hidden universes in everyday objects, from butterfly wings to snowflakes. Uncov ...

Plants spend most of their lives using photosynthesis to make energy. However, in the earliest phase after a seed begins to grow, they cannot yet ...

Fibroblasts are the quiet workers of the skin. They help build collagen and other support fibers in the dermis, the deeper ...

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 ...
