What are the tallest trees in the world
• Ground tissue system: ground tissue provides storage, metabolism, and support. Parenchyma • Large, loosely packed, rectangular cells with thin cell walls. • Responsible for photosynthesis and food storage. • Over 80 % of the cells in non-woody plants. Collenchyma • Elongated cells with uneven, flexible cell walls. • This tissue supports the growth regions of a plant. Sclerenchyma • Cells are short-lived with thick cell walls. • Serves to support the plant. • The cells that give a plant its “woody” characteristics. Lab # 2 • Dermal tissue system: dermal tissue forms the outside covering of plants and provides protection. Epidermis • The outer layer of cells. • Protects the plant and reduces water loss. Stomata • Regulate gases passing into and out of the plant • Usually located on the under side of leaves. • Guard cells regulate the opening by changing water pressure within the cell to swell or shrink. Cork: closely packed cells protecting a woody stem. • Vascular tissue system: vascu
