– Definition: Heterospory is the production of two distinct types of spores—microspores (male) and megaspores (female)—by a plant. – Significance: 1. Evolutionary Advancement: Heterospory is a precursor to seed development, marking a significant step in plant evolution. 2. Genetic Diversity: It promotes cross-fertilization, enhancing genetic variation. 3. Resource Allocation: Differentiation allows specialization in gametophyte development, optimizing resource use. – Examples: 1. Selaginella 2. Salvinia
