Plant Tissue Systems
Plant tissue systems are composed of cells that are similar and perform a specific function. These tissue types combine to form organs, each of which is specific for a particular function. Plant tissues are organized into three types of tissue systems: the dermal tissue system, the ground tissue system, and the vascular tissue system.
1. Meristematic Tissue: These tissues have the capability to develop by swift division. They assist in the major growth of the vegetation. The meristematic cells are cubical, living cells with a big nucleus. These cells are meticulously crammed with no intercellular spaces. Depending on the section where the meristematic tissues are existing, they are categorized as intercalary, lateral, and apical meristems.
2. Permanent Tissues: These cells have lost their ability to distribute but are specialized to offer elasticity, flexibility, and strength to the plant. These tissues can be further categorized into:
– Simple Permanent Tissue: They can be classified into sclerenchyma, collenchyma, and parenchyma based on their purpose.
– Complex Permanent Tissue: These tissues include phloem and xylem.
3. Dermal Tissue System: Dermal tissue covers and protects the plant.
4. Ground Tissue System: The ground tissue serves as a site for photosynthesis, provides a supporting matrix for the vascular tissue, and helps to store water and sugars.
5. Vascular Tissue System: The vascular tissue transports water, minerals, and sugars to different parts of the plant.
In conclusion, plant tissue systems are crucial for the growth, protection, and survival of the plant. Each tissue system has a unique role and function, contributing to the overall health and development of the plant. Understanding these systems can provide insights into the complex biological processes that enable plants to thrive in various environments..
