Cilia and flagella are evolutionarily conserved, microtubule-based, hair-like organelles that protrude from the cell surface. They are the fundamental units of motion in cellular biology, and also ...
Flagella are primarily used for cell movement and are found in prokaryotes as well as some eukaryotes. The prokaryotic flagellum spins, creating forward movement by a corkscrew shaped filament. A ...
Above, an image of a single mouse sperm acquired with a light microscope is shown. Within this image, the flagellum is marked red. The middle image displays a normal and the lower image an increased ...
Most bacteria have flagella; they are threadlike appendages extending from the surface of many microbes. They help move the organism around, a function called motility, in a rotating motion. Enabling ...
Existence of cellular structures with specific size raises a fundamental question in biology: How do cells measure length? One conceptual answer to this question is by a molecular ruler, but examples ...
One essential component of each eukaryotic cell is the cytoskeleton. Microtubules, tiny tubes consisting of a protein called tubulin, are part of this skeleton of cells. Cilia and flagella, which are ...
Most of us will probably be able to recall at least vaguely that a molecule called ATP is essential for making our bodies move, but this molecule is only a small part of a much larger system. Although ...

A microscopic speck of green algae can trot like a horse. Or gallop. Biophysicist Kirsty Wan compares the gaits of creatures large and small. Moving diagonally opposite limbs, or flagella in this case ...
