-The rose. (signifier and signified)

     Semiotics  is the study of generalized symbols on the communication of human sciences, Saussure (1906) separate the sign into signifier and the  Signifier.

     In the first picture, there is only one rose and it is not a signal.But in the second picture, the rose has a a new meaning because the man is holding the rose and he want to give the rose as a gift to the woman. This picture has a sign which is the rose, so  the rose is a signifier and it's signified love. Both rose in this picture, but why the rose  first picture does not mean anything but in the second picture it represents love ?

     According to semiotics, I know that in the  second picture there is a sign which is the Rose.It is iconic, and  there is signifier and signified make it has a sign.
