Colloid biology
Colloid: a mixture of microscopically dispersed insoluble PARTICLES suspended throughout another substance. The PARTICLES, usually inanimate, have different physical and chemical properties, which determine their characteristics.
BIOcolloid = a mixture of CELLS ! I.e. live particles that sense the environment, respond to it and change with time. Meaning, they are a bit more complex to study and understand. All hands on deck!
