Chemotaxis - Wikipedia
Chemotaxis (from chemo-+ taxis) is the movement of an organism or entity in response to a chemical stimulus. [1] Somatic cells, bacteria, and other single-cell or multicellular organisms direct their movements according to certain chemicals in their environment.

2024年11月23日 · Chemotaxis is the phenomenon whereby bacterial cells direct their movements according to certain chemicals in their environment. Explain how chemotaxis works in bacteria that have flagella.
Chemotaxis - an overview | ScienceDirect Topics
Chemotaxis is the directed migration of a cell toward a chemoattractant along a concentration gradient. The ability of neutrophils to undergo chemotaxis implies the possession of a sensory mechanism that must be linked to the locomotor apparatus of the cell.
Chemotaxis - an overview | ScienceDirect Topics
Chemotaxis is defined as a cell behavior where cells detect extracellular signal gradients through receptors, leading to directional movement. Prokaryotes and eukaryotes utilize different mechanisms to achieve chemotaxis by moving in response to chemical gradients.
Chemotaxis, chemokine receptors and human disease - PMC
Chemotaxis is the phenomenon in which the direction of a cell's locomotion is determined by an extracellular gradient of chemicals. The first recorded observations of chemotaxis were made in 1888 by Leber, who found that leukocytes converge from all directions along straight paths to sites of rabbit corneal irritation [1,2]. This observation ...

2025年1月11日 · Chemotaxis is a biological process that enables cells to navigate their environment by moving toward or away from chemical stimuli. This ability allows organisms to find nutrients and escape harmful substances.
Eukaryotic Chemotaxis at a glance - PMC - PubMed Central (PMC)
Chemotaxis is a fundamental process in which cells migrate directionally when they are exposed to external chemical gradients. It is exhibited by a wide variety of cell types and involves distinct strategies that depend on the environmental conditions.
Chemotaxis - an overview | ScienceDirect Topics
Chemotaxis is the directed movement of cells (or an organism) towards or away from a chemical source. A classical example of chemotaxis is the movement of immune cells, such as neutrophils or macrophages, towards chemoattractants released at …
