There are several types of seeds, each with unique characteristics. The most common types are dicot and monocot seeds. Dicot seeds, like those of beans and sunflowers, have two seed leaves, or cotyledons, which help nourish the plant as it grows. Monocot seeds, such as corn and wheat, have only one cotyledon and typically feature a more fibrous root system.
Another important classification is open-pollinated and hybrid seeds. Open-pollinated seeds can produce plants that are true to type, meaning they will grow into plants similar to their parent. In contrast, hybrid seeds are created by crossbreeding different plants, often resulting in higher yields but requiring farmers to buy
