Tunica corpus theory is connected with (a) root apex (b) root cap (c) shoot apex (d) secondary growth.
Option C The tunica corpus concept was given by Schmidt (1924) which was based on plane of divisions of cells. According to this concept there are two portions in shoot apextunica and corpus. The tunica shows only anticlinical divisions and thus it is responsible for surface growth. The corpus shows divisions in all plane and thus responsible for volume growth.
