If a thin slice is taken from any part of a plant and observed under a microscope, it is found to be composed of many chambers or compartments resembling the chambers of a honeycomb. Each of these chambers is called a cell. A plant cell has usually an outer firm non-living boundary [...]
The upcoming discussion will update you about the difference between dicot and monocot stem. Difference # Dicot Stem: 1. Ground tissue in dicotyledonous stem is well-differentiated into extra-stelar and intra-stelar regions. Extra-stelar ground tissue is differentiated into three zones:—collenchymatous hypodermis, parenchyma and starch sheath; and intra- stelar ground tissue consists of pericycle—homogeneous or heterogeneous, large medulla and medullary rays. 2.

Meristematic cells have some distinctive features. They are usually isodiametric and compactly arranged without leaving intercellular spaces. Cells have dense cytoplasm, very small vacuoles and quite prominent nuclei. Plastids are in the pro-plastid stage and ergastic matters are usually absent. Walls are thin, homogeneous and made of cellulose (Fig. 135). These are the characters of truly meristematic cells; departures are [...]
