The main purpose of a seed is to ensure the reproduction and dispersal of plants. Seeds are the product of fertilized ovules and contain the necessary genetic material to develop into new plants. They serve as a means of propagation, allowing plants to grow in diverse environments and conditions. Seeds also provide a food source for the developing embryo and typically possess a protective outer layer to safeguard against adverse conditions. By dispersing via wind, water, or animals, seeds can spread to new locations, facilitating species continuation and adaptation over time in different habitats.
