Meristematic tissues
Responsible for production of new cells
Found in tips of growing stems and roots Apical Lateral

Fundamental tissue
Parenchyma Thin-walled, no secondary walls Contain most of chloroplasts Store food and water

Fundamental tissue
Collenchyma Similar to parenchyma Elongated and irregularly thickened Provides support

Fundamental tissue
Sclerenchyma Derived from Greek, meaning “hard” Dead cells with thick cell walls Strengthen the plant body

Vascular tissue
Transport Xylem
