        Mangroves

        Mangrove plants are incredibly important for shoreline protection and fish habitats.  In this video, Jonathan investigates life in mangroves by visiting both Caribbean and Pacific mangroves and learns the importance of mangroves, as well as the special mechanisms these plants have evolved to survive in salty water. This lab activity is a demonstration of osmosis in plant cells and looks at how saltwater can affect the living material of a "freshwater plant" by comparing potato slices placed in both fresh and saltwater.
