The innermost wall layer of microsporangium is known as tapetum.it provides nutrition to the developing microspores. cells of tapetum possess dense cytoplasm and generally have more than one nucleus.

tapetal cells become bi-nucleate by multiple cell fusions of uni-cellular cells.thus tapetal cells are syncitium (cells hving more than one nucleus) .
