The correct Answer is:
To solve the question regarding the characteristics of seeds in dicots and monocots, we will analyze each statement provided in the question. ### Step-by-Step Solution: 1. **Understanding the Definitions**: - **Dicots**: These are plants that have seeds with two cotyledons. - **Monocots**: These are plants that have seeds with one cotyledon. 2. **Analyzing Statement i**: - "The scutellum is cotyledon in dicots." - **Evaluation**: This statement is incorrect. The scutellum is indeed a cotyledon, but it is found in monocots, not dicots. 3. **Analyzing Statement ii**: - "Generally, dicots have non-endospermic seeds." - **Evaluation**: This statement is generally correct. Most dicot seeds do not retain the endosperm in the mature seed, meaning they are non-endospermic. However, there are exceptions, such as castor seeds, which can be endospermic. 4. **Analyzing Statement iii**: - "Coleoptile covers the plumule in monocots." - **Evaluation**: This statement is correct. The coleoptile is a protective sheath that covers the plumule (the shoot) in monocot seeds. 5. **Analyzing Statement iv**: - "The heart-shaped embryo is seen in monocots." - **Evaluation**: This statement is incorrect. The heart-shaped embryo is characteristic of dicots, not monocots. ### Conclusion: Based on the evaluations: - Statement ii and iii are correct. - Statements i and iv are incorrect. Thus, the correct statements about the seeds of dicots and monocots are: - ii. Generally, dicots have non-endospermic seeds. - iii. Coleoptile covers the plumule in monocots. ### Final Answer: The correct statements are ii and iii. ---
