GTAC Staining Plant Stem Sections Page 1 of 6 Stain Dicot and Monocot Stem Sections Introduction Cellulose is the main component of all plant cell walls, and is the most abundant organic compound in most plants. . The stem is answerable for supporting the complete plant and helps it to realize daylight as quite a bit as doable for photosynthesis. To examine the tissues clearly, it is desirable to stain the section with suitable stains, as different stains colour the tissues differently. Those that start with one leaf are monocots. 20.
