**Characteristic feature of dicotyledonous seeds: The embryo possesses one seed leaf (cotyledon)**
Dicotyledonous seeds are seeds that come from angiosperms (flowering plants) belonging to the class Magnoliopsida. These seeds have several characteristic features, and one of the most distinctive features is that the embryo possesses one seed leaf or cotyledon.
**Explanation:**
1. **Cotyledons:** Cotyledons are the first leaves that emerge from the embryo of a seed. In dicotyledonous seeds, the embryo possesses two cotyledons. These cotyledons serve as a food source for the developing seedling until it becomes photosynthetically active. They are usually thick and fleshy in nature.
2. **Embryo:** The embryo is the tiny, undeveloped plant inside the seed. In dicotyledonous seeds, the embryo possesses two cotyledons. However, the statement in the question is incorrect as it states that the embryo possesses one cotyledon.
3. **Endosperm:** The endosperm is a tissue that provides nourishment to the developing embryo in some seeds. In dicotyledonous seeds, the endosperm is present but is usually not well-developed. Instead, the cotyledons take over the role of storing and supplying nutrients to the growing seedling.
4. **Seed coat:** The seed coat is the protective covering of the seed. It is formed from the outer layer of the ovule after fertilization. In dicotyledonous seeds, the seed coat is present and serves to protect the embryo and its food reserves from damage and desiccation.
In summary, the correct characteristic feature of dicotyledonous seeds is that the embryo possesses two seed leaves or cotyledons. This feature distinguishes them from monocotyledonous seeds, which have only one seed leaf. The endosperm in dicotyledonous seeds is usually not well-developed, and the seed coat is present for protection.
