The first type is found in Zephyranthes sp. One of the layers gives rise to the stele and the other to the cortex and root cap.

The derivatives of dermatogen vary. Anticlinal division is the characteristic of tunica whereas tbeory exhibits both anticlinal and periclinal division. Korper and kappe-these two zones of root are delimited by planes of cell division. The body-cap concept is illustrated below on analyzing the divisions in the derivatives of apical cell Fig. This is a question and answer forum for students, teachers and general visitors for exchanging articles, answers and notes. The two cells thus formed one has the capability of cell division.

Composition of Sporopollenin in Spores and Pollen Plants. When such division continues it is observed that a single rowed theogy is left behind over the double-rowed region. Continuous T-divisions result in the formation of double-rowed region over a single rowed region. This theory was proposed by Nageli who drew the attention to the occurrence of a single apical cell or apical initial that composes the root meristem.

Top 3 Theories of Root Apical Meristem in Plants | Botany

The inner region of the apex is the korper. Anybody can ask a question Anybody can answer The best answers are voted up and rise to the top.

Apical cell theory is confined to vascular cryptogams only as the root apical meristem of flowering plants does not have a single apical cell. In the korper the initial cell first divides by transverse partition and forms two cells. It is the T-division that characterizes korper and kzppe. It is similar to the tunica-corpus theory of the shoot apex.

Top 3 Theories of Root Apical Meristem in Plants | Botany

The cells of this region divide first horizontally. Such divisions are described as T-divisions. According to Hanstein root apical meristem consists of three cell-initiating regions called histogens Fig.

The zones exhibit clear boundary when they originate from separate initials, e. This theory of root ttheory 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. Answer Now and help others.

The root meristem exhibits multicellular structure.

Megasporogenesis and Megagametogenesis in Plants Embryology Biology. In certain members of the families Juglandaceae, Rosaceae, Leguminosae, Koorper etc. The zones do not exhibit sharp demarcation line when they are the derivatives of same apical cell. This is a question and answer forum for students, teachers and general visitors for exchanging articles, answers and notes.

The third type is found in Haemanthus coccineus. In this region the T is inverted, i. In Zea mays monocot dermatogen generates korpe cap only and this histogen is referred to as calyptrogen.

Thory this type, three groups of initials are found at the apex — outer dermatogenmiddle periblemand inner plerome. This type is found in majority of dicotyledonous plants. The other three sides donate cells to form epidermis, cortex and vascular cylinder.

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. Answer Now and help others.

The theory was put forward by Schuepp In other words all tissues that compose kapps mature root including root cap are the derivatives of a single apical cell. In this type there is a single row of initials which, ultimately, gives rise to various zones of the root including the root cap.
