1. Enhanced Protection and Nourishment: Seeds have a protective outer layer (seed coat) that shields the embryo from harsh environments and helps prevent desiccation (drying out). They also contain a food source (endosperm) to nourish the developing embryo until it can establish its own roots and leaves. Spores, in contrast, are single cells with little to no protective covering or food reserves. This makes them more vulnerable to environmental stress.

2. Increased Dispersal Potential: Seeds often have adaptations that enhance their dispersal, such as wings, hooks, or fleshy fruits that attract animals. This allows them to travel further from the parent plant, reducing competition and increasing their chances of finding suitable germination sites. Spores, on the other hand, rely mainly on wind or water for dispersal, which is less efficient and can limit their spread.
