    This Is The Happiest Blade Of Grass You Will Ever See

    So happy.

    This is the cross section of a blade of marram grass.

    Dr Phil Gates /

    It's the type of grass you typically find in sand dunes in coastal areas of the U.K. The leaves roll up to protect themselves from periods of drought. And the cells inside them look very, very happy about that.

    It doesn't look quite as happy close up.

    Dr Phil Gates /

    The 'eyes' in the face are tubes that transport water through the leaf. The blue 'mouth' is the phloem, made of a series of smaller tubes, that transports sugar made by photosynthesis out of the leaf.
