Correct answer: A. Planes of cell division
- A. Planes of cell division
- B. Regions of meristematic activity
- C. Rate of cell growth
- D. Rate of shoot tip growth
Explanation
The tunica corpus concept was given by Schmidt (1924) which was based on a 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 planes and is thus responsible for volume growth.
