The _____ cells contain air spaces to allow the movement of gases (i.e. Upper Epidermis . When photosynthesis takes place, water that has been absorbed by the tree's roots is carried to leaves where it comes in contact with the layers of chlorophyll. Atmospheric Carbon Dioxide . Oxygen. Short answer: Mainly in the leaf “topside” mesophyll cells. Structure of Plant Leaves Photosynthesis comes from Greek and means ‘putting together with light.’ While we humans are trying hard these days to harness the sun’s energy to power our homes and vehicles, every green leaf in the world is making the most of solar energy to ‘put together’ food from water and carbon dioxide.
