The following points highlight the two types of secondary tissues in dicot root of Plants. The types are: 1. Secondary Vascular Tissues 2. Secondary Ground Tissues or Periderm. Type # 1. Secondary Vascular Tissues: Stage I: Conjunctive parenchyma cells lying on the inner edges of the primary phloem bundles become meristematic. They give rise to small quantity of secondary xylem [...]
The following points highlight the six main parts of monocot root in plants. The parts are: 1. Epiblema 2. Cortex 3. Endodermis 4. Pericycle 5. Vascular Strand 6. Pith. Monocot Root: Part # 1. Epiblema or Piliferous Layer (Rhizodermis): It is the outermost layer of young root which has thin-walled cells. Some of the cells give rise to root hairs. [...]
The upcoming discussion will update you about the difference between Meristematic and Permanent Tissues. Difference # Meristematic Tissues: 1. It is a simple tissue. 2. The cells are small and isodiametric. 3. Vacuoles are either small or absent. 4. Crystals and other cell inclusions are absent. 5. Respiratory and biosynthetic activities are very high. 6. Intercellular spaces are very small [...]
