During embryo germination in the grass family, the absorptive organ that forms an interface between the embryo and the starchy endosperm tissue is called the scutellum.

The scutellum is a specialized structure found in the seeds of grasses (family Poaceae) and serves as the primary absorptive organ during germination. It is a shield-shaped structure located on one side of the embryo, specifically on the side facing the endosperm. The scutellum is rich in enzymes that break down complex carbohydrates into simpler forms, facilitating their absorption by the developing embryo.

As the seed germinates, the scutellum secretes enzymes such as amylases that hydrolyze the starch stored in the endosperm into sugars. These sugars are then transported to the growing embryo, providing it with a source of energy and nutrients for growth and development.

The scutellum plays a crucial role in the early stages of seed germination in grasses and is an essential adaptation for these plants to utilize the stored nutrients in the endosperm and ensure successful seedling establishment. Hence, the correct answer is option 3.
