Abstract:
Plant cell wall is composed of three layers viz. Intercellular substance or the middle-lamella, the primary wall and the secondary wall. Parental primary walls from the cambial zone of pinus are the intercellular material comprising not only the cell plate originally laid down across the initial but also any remnants of early primary walls. The tangential wall separating each pair in a group of four is thicker than the wall between each cell. Similarly the tangential wall between groups of four is thicker than between pairs but remains constant on continued division, thus making it possible to detect both sanio`s four and the enlarging four under the microscope. The radial walls increase in thickness by one primary wall for each group of four laid down in the xylem and the same applies to the outer wall of the initial. Mathematical correlation between the number of walls along the radial face of a group of four and number of initial division in the series W = 3+n where W is the number of walls along the radial face of any group of four; 3 represent the 3 walls present along the radial face of the first sanio`s four in the series and is the number of initial divisions sine the series begin.
