Stomata: These are small openings or pores used by plants for gas exchange. They're like our nostrils!
Photosynthesis:This is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of carbon dioxide and water. It's like cooking a meal using only sunlight, CO2, and water.
Xylem: This is plant tissue that transports water and nutrients from roots to leaves. Think of it as the plant's plumbing system.
