In this article we will discuss about the external morphology of oedogonium. 1. Plant body consists of green, narrow, unbranched (Fig. 24) and multicellular filaments. 2. Cells are cylindrical and arranged end to end in each filament. 3. All the cells of the filaments are similar in shape except lowermost holdfast and uppermost apical cell. 4. Uppermost apical [...]
In this article we will discuss about the external morphology of coleochaete with its reproductive structure. 1. Plant body is thalloid, multicellular and of two types: (a) Cushioned forms; (b) Discoid forms. 2. Cushioned forms, such as Coleochaetepulvinata show clear heterotrichous habit with a prostrate and an erect system (Fig. 23 A). 3. Erect system is very much branched [...]
In this article we will discuss about the anatomy of sargassum. Insert the material (axis, leaf, air bladder) in pith, cut its transverse sections, stain in safranin, wash with water, mount in glycerine and study under microscope. T.S. Axis: 1. Axis is differentiated into meristoderm, cortex and medulla (Fig. 40). 2. Meristoderm is the outermost layer made up of closely-packed, [...]
