What is apospory in plants?

Answer

Apospory is a form of asexual reproduction in plants where the gametophyte develops directly from sporophytic tissue without undergoing meiosis. In this process, diploid cells from the sporophyte (typically from the nucellus or integument) develop into gametophytes without the reduction division that normally produces haploid spores. This results in diploid gametophytes rather than the typical haploid ones. Apospory is commonly observed in some ferns and seed plants, and it represents an alternative reproductive pathway that bypasses the normal alternation of generations. This mechanism allows plants to reproduce without fertilization and maintain genetic stability across generations.
