Motile: meaning, definitions and examples
π
motile
[ ΛmoΚtaΙͺl ]
biology movement
Motile refers to the capability of an organism to move spontaneously and actively, consuming energy in the process. This term is often used in biological contexts to describe organisms that possess self-directed movement, such as animals and certain microorganisms. It contrasts with 'sessile,' which refers to organisms that remain fixed in one place. Motile organisms can navigate their environment, find food, escape predators, and engage in reproductive behaviors, contributing to their survival and adaptation in various ecosystems.
Synonyms
Examples of usage
- Many motile species migrate during seasonal changes.
- Motile bacteria use flagella to swim through liquid.
- Most animals are motile at some stage of their life cycle.
Word origin
The term 'motile' originates from the Latin word 'movere,' which means 'to move.' It was first used in scientific literature in the 19th century to describe organisms capable of independent movement. Over time, the term became widely adopted in fields such as biology, zoology, and ecology. The concept of motility is crucial in understanding organism behavior, evolution, and ecological interactions. As biological research progressed, the distinction between motile and sessile organisms helped scientists categorize species based on their mobility and lifestyle. Today, 'motile' is a fundamental term used in the study of life sciences, highlighting the importance of movement in the natural world.
