Question

In Korper- Kappe theory,
A. Korper refers to manthe and kappe to body.
B. Korper is cortex while kappe is cap.
C. Korper is calyptrogens while kappe is the rest of the meristem.
D. Korper is equivalent to corpus and kappe to tunica.

Answer 1

According to Korper-Kappe theory, the cells in the root apex divide in a T-shaped pattern. The outer part of the root apex is called the Kappe and the cells here divide horizontally first and the lower cell divides longitudinally.
This theory was proposed by Schuepp (1917).
This theory is comparable with the tunica and corpus theory of shoot apex.

Complete answer:
korper-kappe theory.
According to tunica-corpus theory, shoot apex is divided into two tissue zones known as tunica and corpus.
The shoot apex is composed of two layers of cells of tunica and corpus (layer L1, L2 and L3 to denote the outer layer of tunica, the inner layer of tunica and corpus respectively).
According to Korper-Kappe theory, the cells in the root apex divide in a T-shaped pattern.
The outer part of the root apex is called the Kappe and the cells here divide horizontally first and the lower cell divides longitudinally (right angles to the plane of the first division).
The inner part of the apex is the Korper.
And the cells in this region form an inverted T pattern as here the second division takes place in the upper cell.
So, the correct answer is 'Korper is equivalent to corpus and kappe to tunica'.

Note: Difference between shoot apex and root apex.
Shoot apex
1. It is truly is terminal
2. it is comparatively long
3. It is dome shaped
4. Quiescent centre is not distinguishable.
5. Shoot apex is covered by juvenile leaves.
Root apex
1. It is truly sub terminal
2. It is quite short
3. Root apex is cup shaped in outline.
4. Quiescent centers occur in many root apices
5. It is protected by a root cap.
