Transpiration

the pipes moves food back down through the plant.
StomataThere are tiny openings on the undersides of a leaf known as stomata. Air moves in and out of a leaf through these openings.
Oxygen moves through leafy plants through the "stoma, pleural: stomata". They are small pores in the leaf that can open and close to allow gas exchange. However, most plants exhale oxygen (O2) and inhale carbon dioxide (CO2), so oxygen is generally leaving a plant.

Stomata Vascular tissue, specially the phloem
Transpiration
Phloem is the vascular tissue that which food moves through
the pipes moves food back down through the plant.
Many services of a plant are covered with pores called stomata. Transpiration is a process by which water moves through plant and evaporates through these pores. This is necessary to allow carbon dioxide to also flow through stomata for photosynthesis.
