Metazoa Meaning and Definition
Metazoa
Pronunciation
/ˈmɛtəzoʊ.ə/
Part of Speech
Noun
Definition
A kingdom of multicellular animals, characterized by the presence of specialized cells, tissues, and organs. Metazoa are eukaryotes that exhibit complex body structures and behavioral adaptations.
Examples
- Humans, along with other animals, belong to the kingdom Metazoa.
- Metazoa include a wide range of species, from simple sponges to complex mammals.
Synonyms
- Animals
- Multicellular organisms
Antonyms
- Protists
- Monera
Additional Information
Metazoa are characterized by their complex body structures, which allow for a wide range of functions and behaviors. They exhibit tissue organization, development from embryonic stages, and respond to stimuli through nervous systems. Metazoa also have the ability to move, feed, and reproduce, which distinguishes them from other eukaryotic organisms.
Metazoa are found in diverse environments, from marine ecosystems to terrestrial habitats. They have evolved complex adaptations, such as sensory organs, muscle systems, and immune responses, which enable them to survive and thrive in their environments.
The study of Metazoa has significant implications for our understanding of evolutionary biology, developmental biology, and conservation. By studying the diversity of Metazoa, scientists can gain insights into the origins of life, the evolution of complex traits, and the conservation of ecosystems.
Eymology
The term “Metazoa” comes from the Greek words “meta,” meaning “beyond” or “after,” and “zoa,” meaning “animals.” This name reflects the complex organization and development of multicellular animals, which distinguishes them from other eukaryotic organisms.
Usage Notes
The term “Metazoa” is often used in scientific and academic contexts to refer to multicellular animals. In general language, it may be less common to use this term, and “animals” or “multicellular organisms” may be preferred. However, in discussions of evolutionary biology, developmental biology, or conservation, the term “Metazoa” can provide a more specific and technical distinction.
Cultural References
Metazoa have appeared in various cultural contexts, such as in literature, art, and film. For example, the film “The Tree of Life” (2011) explores the evolution of Metazoa on Earth, while the novel “The Selfish Gene” (1976) by Richard Dawkins discusses the concept of Metazoa in the context of evolutionary biology.
Idiomatic Expressions or Phrases
No idiomatic expressions or phrases commonly include the term “Metazoa.” However, it may be used in scientific or academic contexts to refer to the diversity of multicellular animals.
