The earliest physical evidence of the site of a newly forming leaf primordium would be 7) _______ A) formation of stomata in the epidermal layer of the shoot apical meristem. B) cell division in the shoot apical meristem with the newly forming walls perpendicular to the surface of the meristem. C) development of chloroplasts in a surface cell of the shoot apical meristem. D) elongation of epidermal cells perpendicular to the surface of the shoot apical meristem.
