These cells seldom divide. Hanstein in advocated the theory. Apical Cell Theory gheory. Answer Now and help others. Anticlinal division is the characteristic of tunica whereas corpus exhibits both anticlinal and periclinal division.

The inner region of the apex is the korper.

The initial cell divides transversely. In this type, three groups of initials are found at the apex — outer dermatogenmiddle periblemand inner plerome.

It is based on differences in the planes of cell division. In the korper the initial cell first divides by transverse partition and forms two cells. thery

In Korper-Kappe theory

Here’s how it works: The body-cap concept is illustrated below on analyzing the divisions in the derivatives of apical cell Fig.

The mappe initial is tetrahedral in shape and generates root cap from one side. The boundaries between korper and kappe, and between tunica and corpus are not always sharply demarcated. This type is found in majority of dicotyledonous plants. In Brassica dicot dermatogen generates both protoderm and root cap and this histogen is referred to as dermatocalyptrogen.

The Korper-Kappe Theory of Root Apex | Essay | Botany

It consists of conspicuous longitudinal files of cells. A single apical cell is present only in vascular cryptogams, e. During growth the root changes in diameter. This is a question and answer forum for students, teachers and general visitors for exchanging articles, answers and notes. In this region the T is inverted, i.

The Korper-Kappe Theory of Root Apex | Essay | Botany

The theory was put forward by Schuepp The korper-kappe theory of root apex is comparable with tunica-corpus theory of shoot apex. The central part of root cap theoory the columella where the cells are arranged in longitudinal files.

It divides longitudinally and the two daughter cells thus formed have the potentiality of cell division. It is similar to the tunica-corpus theory of the shoot apex.

In contrast to that of the shoot apex, the apical meristem of the root apex morper cells not only toward the axis but also away from it to form the root cap. One of the layers gives rise to the stele and the other to the cortex and root cap. It is the T-division that characterizes korper and kappe. Such divisions are described as T-divisions.

This type of division has been found among the members of Gramineae and Fagaceae. Here’s how it works: This theory of root throry was proposed in by Schiiepp who regarded the occurrence of two systems of cell seriation that characterize the root apex with reference to planes of cell division in its parts. This cell divides kapoe and both the daughter cells inherit the property of cell division. Though histogen theory is abandoned to explain shoot apex, Eames and MacDaniels illustrated the root apical meristem on the basis of histogen concept.

The lower daughter cell then divides longitudinally, i. Megasporogenesis and Megagametogenesis in Plants Embryology Biology. In this type there is a single row of initials which, ultimately, gives rise to various zones of the root including the root cap.

The theory says that the korpper in the root apex divide in a pattern called T-divisions. The daughter cells are parallel in arrangement, share a common wall and divide by transverse partition followed by longitudinal partition in one cell.

The root apex forms no branches, and no lateral structures like the leaves. The two cells thus formed have the capability of cell division. The daughter cells divide by transverse partitions followed by longitudinal partitions. In the fourth additional type, there are four rows of initials giving rise to the root cap, the epidermis, the cortex and the stele, independently.
