The seedleaves, or cotyledons, can also hold a food supply. The food supplysupports the sprouting seedling until it grows a root and can makeits own food.it is not surprising that seeds are an excellentsource of nutrient, beacuse it contains whole amount of nutrientsin them. Seeds contain all the starting materials necessary todevelop into complex plants. Because of this, they are extremelynutritious. Seeds are great sources of fiber.
