Apical cell theory was given by Hofmeister Hanstein Haberlandt Grew Answer: 1 Q2. Ground meristem develops into the pith. Meristematic zone: contains protoderms (epiderm), procambium (primary vascular tissue) and ground meristem (cortex and pith). SAM gives rise to three types of tissues such as 1) protoderm, 2) procambium, … The cells are highly meristematic and undergo frequent mitoses. Ground meristem is regarded as the precursor of fundamental or ground tissue system. Ground meristem represents the undifferentiated meristematic tissue of primary meristem from where ‘protoderm and primary procambial strands have been segregated’- Haberlandt (1914). Privacy Policy3.

SAM tissue is totipotent that possesses the plasticity to produce and differentiate other types of cells. ... respectively. The shoot apical meristem, found above ground, is composed of undifferentiated cells that have one of three destinies. The categories are: 1. Protoderm 2. Mesophyll cells of leaf and additional procambial bundles also originate from ground meristem. The apical meristems produce tissues called primary meristems: the protoderm, the ground meristem, and the procambium. The root meristem forms the basal end. 7.2 and the cell lineages of their formation are illustrated in box 7.1. Apical meristem has two parts into-promeristem zone which contains actively dividing cells, and therefore the meristematic zone which contains protoderm, procambium, and ground meristem.
