slime mould
Học thuậtThân thiện
Definition
Noun: A simple organism that exists as a naked, mobile mass of protoplasm. It exhibits behaviors and characteristics associated with both animals (like movement and feeding) and fungi (like spore production), leading to its historical classification challenges. It is often found in damp, decaying organic matter.
Usage and Examples
- Noun:
- Under the microscope, the slime mould extended finger-like projections to explore its environment.
- Biologists study slime mould because it can solve complex problems, such as finding the shortest path through a maze.
- A bright yellow slime mould appeared on the rotting log after the rain.
Advanced Usage and Notes
- Scientific Classification: While once considered fungi, slime moulds are now typically classified within the kingdom Protista (or Protoctista), highlighting their unique biological status.
- Life Cycle: The term often refers to the feeding, motile stage (plasmodium) of the organism's life cycle. It later develops into a stationary, spore-producing structure.
- Research Context: In advanced biology and computing, slime moulds are cited as models for decentralized problem-solving and network optimization due to their adaptive growth patterns.
Variants and Related Words
- Slime mold: The alternative American English spelling.
- Myxomycete: The formal scientific term for organisms in the division Myxomycota.
- Plasmodium: The specific name for the multinucleate, amoeboid feeding stage of a slime mould.
Synonyms
- Myxomycete (scientific synonym)
- Acellular slime mould (for the plasmodial type)
- Cellular slime mould (for the aggregative type, e.g., )
Related Phrases and Terms
- Plasmodial slime mould: A type that forms a large, single-celled structure with many nuclei.
- Cellular slime mould: A type where individual amoebae aggregate to form a multicellular structure during part of its life cycle.
- Slime mould intelligence: A phrase used in biomimicry and unconventional computing to describe the organism's problem-solving abilities without a central nervous system.
Noun
- a naked mass of protoplasm having characteristics of both plants and animals; sometimes classified as protoctists
