Correct answer: True
The cotyledons of castor are big storage of food, which is rich in vitamins, fats, protein, and carbohydrates. These cotyledons provide nutrients to the embryo at the time of seed germination.
In the monocots plants scutellum is found, which is directly connected to the embryo, which provides nourishment to embryo via endosperm. A large amount of food is stored in the endosperm, at the time of germination aleurone secrets enzyme that helps the plant to grow and provide nourishment to the developing embryo.
Hence, the given statement is true.
