The tissue in monocot root is divided into three layers: epidermis, cortex, and vascular tissue.
1. Epidermis:
- Parenchyma cells – they are the most abundant cells in the epidermis and function in storage, photosynthesis, and secretion
- Root hair cells – they are specialized epidermal cells that increase the surface area of the root for water and nutrient absorption
- Sclerenchyma cells – they provide mechanical support and protection to the root
2. Cortex:
- Parenchyma cells – they are the most abundant cells in the cortex and function in storage, photosynthesis, and secretion
- Endodermal cells – they form the innermost layer of the cortex and regulate the movement of water and nutrients into the vascular tissue
- Sclerenchyma cells – they provide mechanical support and protection to the root
- Collenchyma cells – they provide flexible support to the root
3. Vascular tissue:
- Xylem cells – they transport water and minerals from the roots to the stem and leaves
- Phloem cells – they transport sugars and other organic molecules from the leaves to the roots and other parts of the plant
- Companion cells – they provide metabolic support to phloem cells
- Parenchyma cells – they are present in both xylem and phloem and have various functions such as storage, secretion, and support.
