An advantage for the angiosperm approach to the formation of nutritive tissue is in energy conservation. The nutritive tissue is formed via double fertilization in Angiosperms. The advantage of double fertilization is that the plant does not invest energy in seed nutritive tissue until after an egg has been fertilized. This means that endosperm (nutritive tissue) starts to develop and store nutrients after it has been fertilized by a sperm cell. Another advantage is that the endosperm nucleus is very active and divides rapidly, so it forms the nutritive tissue very quickly.

Explanation:

The Langerhan's cells arise from the bone marrow and migrate to the epidermis. The Langerhan's cells are the body's first line of defense and play a significant role in antigen presentation. They need special stains to be visualized and are primarily found in the stratum spinosum. These are the mesenchymal origin obtained from CD34 positive stem cells of bone marrow and are part of the mononuclear phagocytic system.
