单词 colony
释义
colony

Biology
  • 1. (in zoology) A group of animals of the same species living together and dependent upon each other. Some, such as the corals and sponges, are physically connected and function as a single unit. Others, such as insect colonies, are not physically joined but show a high level of social organization with members specialized for different functions (see caste).

    2. (in microbiology) A group of microorganisms, usually bacteria or yeasts, that are considered to have developed from a single parent cell. Colonies that grow on agar plates differ in shape, colour, surface texture, and translucency and can therefore be used as a means of identification.
