Definition

1. Adjective:
   • Relating to or characterized by apogamy: Pertaining to a form of asexual reproduction in plants where an embryo develops from a cell of the gametophyte (such as an egg cell) without fertilization by a male gamete.

Usage

• The term is used primarily in botanical and biological contexts to describe a specific reproductive process.
• It functions as an attributive adjective, typically modifying nouns like "development," "reproduction," or "species."

Examples

• The fern species exhibited apogamic reproduction, allowing it to spread without the need for pollination.
• Researchers studied the apogamic development of the embryo in certain flowering plants.

  • The formation of an apogamic embryo bypasses the usual fertilization event.
• Apogamic species: A plant species that reproduces primarily or exclusively via apogamy.

Synonyms
