Plant tissues

Learning goals We are learning about the cells of plants. We are learning to identify the main tissues in plants.

Meristematic cells Unspecialized plant cells Divide & differentiate into specialized cells

Plant tissues

Dermal tissue Forms the outermost layer of a plant Periderm tissue:   Periderm tissue: Only on woody plants Forms bark on stems and large roots Epidermal tissue: Thin layer of cells covering the surface of leaves, stems and roots

epidermal Can be specialized Leaf cells produce a waxy waterproof cuticle Root hairs to absorb water and minerals

Vascular tissue transportation system Vascular bundle (veins) Xylem: Transports water and dissolved minerals from roots to the leaves   Phloem: Transports a sugar solution from the leaves to the roots

Ground tissue Located between dermal and vascular tissue Variety of functions: Photosynthesis Food and water storage Structural support

2 main types of Ground tissue Palisade layer: main site of photosynthesis, near surface Spongy mesophyll: Interior of leaf, photosynthesize, loosely packed
