Plant Adaptations
Xylem: vascular tissue that conducts water and the woody element in the stem.
Phloem: vascular tissue that conducts sugars and other metabolic products (food) downwards from the leaves.
Stomata: any of the minute pores in the epidermus of the lead or stem of a plant, forming a slit of variable width that allows movement of gases in and out of the intercellular spaces.
