• Lower Epidermis: contains stomata cells and prevent water loss
• Upper Epidermis: a single layer that reduces water loss
• Palisade layer:spongy layer that allows air to pass through
• Cuticle: outer layer of tissue
• Stoma: pores in the leaf, allows gases in and out.
• Guard Cells: surrounds the stroma and regulate transportation
• Vein: framework of conducting and supporting tissues
• Spongy Layer: area with loosely packed cells allows for gas exchange
• Air Space: gas enter and exit the leaf through the stroma
• Xylem: transport water from roots to shoots
• Phloem: vascular tissue in plant that conduct sugar.
• Chloroplasts: plastid that contains chlorophyll
• mesophyll: contains chloroplasts, is the inner tissue
