Definition

Noun: 1. A taxonomic subclass of flagellate protozoans: In some biological classification systems, Subclass Zoomastigina is a group within the kingdom Protista. Its members are characterized by being flagellates (possessing one or more whip-like flagella for movement) and having a holozoic (ingesting solid food particles) or saprozoic (absorbing dissolved organic matter) mode of nutrition.

Usage Notes

• The term is a specialized scientific term used in taxonomy (the science of classification). It is primarily used in academic, biological, and microbiological contexts.
• This classification is not universally used in modern taxonomy, as protist classification is frequently revised. It represents a historical or alternative grouping for certain zooflagellates.

Examples

• Scientific Description:
  • The Subclass Zoomastigina includes many parasitic species, such as Trypanosoma.
  • Organisms classified under Zoomastigina lack chromatophores, distinguishing them from photosynthetic flagellates.

Advanced Usage

• The group is often contrasted with the (or similar groups), which contain flagellates with chloroplasts for photosynthesis.

Variants and Related Words

• Zoomastigophorea (n): A class-level name sometimes used synonymously or to encompass the zoomastigotes.
• Zooflagellate (n): A common name for a non-photosynthetic, typically heterotrophic flagellate protozoan; a member of the .
• Zoomastigote (n): Another term for an organism belonging to this subclass.

Synonyms

• Zooflagellata (in some classifications)
• (Informally) Zooflagellates
