Question

A pathway known as SPAC describes the movement of this molecule. The movement of this molecule occurs via the symplastic and apoplastic routes. This molecule is prevented from entering the stele by the Casparian strip. (15[1])Plasmolysis occurs when this molecule is lost in a (*) hypotonic solution due to a decrease in osmotic (10[1])pressure. The xylem (“zai-LUHM”) transports this substance in vascular plants. (10[1])Transpiration results in the loss of this molecule, which alone with carbon dioxide is an input for photosynthesis. For 10 points, name this molecule that enters plants through roots, with formula H2O. ■END■
