Task: Class Definition Understanding (ontology: Sciences/Biology)

Which of the following definitions best describes 'anther wall tapetum morphogenesis'?

A. Increase in size of antral follicles due to cell proliferation and/or growth of the antral cavity.
B. The process in which the Mullerian ducts, primordia of the oviducts, uterus and upper vagina, undergo regression in male embryos.
C. The process in which a relatively unspecialized cell acquires specialized features of an anther cell wall tapetum cell. The tapetum is a layer of cells that provides a source of nutrition for the pollen grains as they mature.
D. The process in which the anatomical structures of the anther wall tapetum are generated and organized. The anther wall tapetum is a layer of cells that provides a source of nutrition for the pollen grains as they mature.

Answer: The process in which the anatomical structures of the anther wall tapetum are generated and organized. The anther wall tapetum is a layer of cells that provides a source of nutrition for the pollen grains as they mature.
