Detailed explanation-2: -Double coconut: The largest seed in the world.

Detailed explanation-3: -Modern seed sizes range from 0.0001 mg in orchid seeds to 42 kilograms (92 lb 10 oz) in double coconuts. Larger seeds have larger quantities of metabolic reserves in their embryo and endosperm available for the seedling than smaller seeds, and often aid establishment under low resource availability.

Detailed explanation-5: -Seeds come in different sizes and shapes across plant species. They range from dust-sized seeds in orchids to double coconut Lodoicea (yes, coconuts are seeds!). Depending on geographical location and the prevailing biotic and abiotic factors, seed size and shape can vary even within a species.
