Plant Tissue Systems

The tissues of a plant are organized into three tissue systems: the dermal tissue system, the ground tissue system, and the vascular tissue system.

Dermal Tissue System - Epidermis, Periderm (in older stems and roots)
• protection
• prevention of water loss

Ground Tissue System - Parenchyma tissue, Collenchyma tissue, Sclerenchyma tissue
• photosynthesis
• food storage
• regeneration
• support
• protection

Vascular Tissue System - Xylem, Phloem
• transport of water and minerals
• transport of food
