Here's why:
* Dicots are a type of flowering plant that have two seed leaves (cotyledons).
* Cotyledons are the first leaves to emerge from a seed. In dicots, they are the primary storage organs for nutrients like starch, protein, and fats, which are essential for the developing embryo.
* Endosperm, the tissue that surrounds the embryo in some plants and provides food, is usually absent in dicots.
Therefore, the cotyledons serve as the primary food source for the dicot embryo until it can produce its own leaves and perform photosynthesis.
