The triploid tissue that nourishes the developing embryo is called

Explanation:
In flowering plants, the nutritive tissue inside the seed that nourishes the developing embryo is the endosperm. It forms through double fertilization: one sperm fertilizes the egg to produce the diploid zygote, while another sperm fuses with the two polar nuclei to form triploid endosperm. This 3n tissue stores nutrients such as starch, oils, and proteins to feed the embryo during germination. The zygote itself grows into the embryo, the young plant. The seed coat is a protective outer layer derived from maternal tissue, not a nutrient source, and the embryo is the developing plant rather than the nutrient store.
