name cell types that make up each tissue and describe the function in monocot root and they develop from primary meristem
The monocot root is composed of three primary types of tissues: the epidermis, cortex, and stele.
1. Epidermis: The epidermis is a single layer of specialized cells that protect the root from water loss and infection. It also helps in the absorption of water and nutrients.
2. Cortex: The cortex is the outer tissue layer of the root that lies between the epidermis and the stele. It consists of parenchyma cells that store food and water. The cortex also plays an important role in regulating the movement of water and nutrients.
3. Stele: The stele is the central core of the root and is surrounded by the cortex. The stele consists of several distinct parts, including the endodermis, pericycle, and vascular tissues. The endodermis is a specialized layer of cells that regulates water and nutrient uptake by controlling their movement into the stele. The pericycle is a layer of cells that gives rise to lateral roots and shoots. The vascular tissues include the xylem and phloem, which transport water and nutrients throughout the plant.
These tissues develop from primary meristem, which is the initial growth tissue in the root. As the root grows, the primary meristem gives rise to the different tissues and structures that make up the mature root.
