Plants have three main tissue system.
1. dermal tissue which is the protective outer covering of a plant. In young plants it consists of single layer called epidermis. A waxy cuticle often covers epidermis and protects against water loss. In older plants, dermal tissue may be many cell layers deep and may be covered with bark.
2. vascular tissue supports the plant body and transports water and nutrients throughout the plant. The two kinds are xylem, a water-conducting tissue, and phloem, a tissue carries dissolved nutrients. Plant fibres such as cotton and linen are produced by the vascular tissue systems of plants. It contains many long, slender cells that form long tubes and have walls that are reinforced by lignin. These characteristics are similar to those of fibres such as cotton and linen. neither dermal or ground tissue consists of cells with these characteristics.
3.ground tissue produces and stores sugars and helps support the plant. It consists of parenchymal cells, collenchyma cells and Sclerenchyma cells.
