Kareem was surprised: "How do you
            mean?' he asked, "When we eat these

            plums, are we really eating the Sun?"

               Grandpa Hassan smiled: "Actually we
            are eating the Sun, but indirectly. We all know
            that the main source of energy on Earth is the
            Sun. But human beings and animals do not use
            this energy directly, because we don't have the right
            systems. Do you know how we use it? Human beings and

            animals can only get usable energy from the nutrients produced in
            plants. The energy we use is really the Sun's energy given to us by
            plants. For example, when we sip tea we are actually sipping en-
            ergy from the Sun; when we chew a piece of bread, there is actu-

            ally a piece of the Sun's energy between our teeth. The strength in
            our muscles is really an altered state of the Sun's energy. Because
            of this energy, you can run and play. So, how do plants manage
            this? Plants perform some complicated operations in order to store
            the Sun's energy for us. What allows plants to produce their own
            food and separates them from other living

            things is that their cells are different from
            the cells of human beings and animals;
            they have structures in their cells that
            allow them to use the Sun's energy di-
            rectly. With the help of these structures,

            they transform the Sun's energy into a
            form that human beings and animals
            can use for food, and
            they store this en-
            ergy in food using
            a special hidden

            formula."
