Mama's plant and Beneatha's hair are two significant symbols in the drama <em>A Raisin in the Sun</em>. The meaning in Mama's plant comes from the fact that the family is symbolized by the plant. In the same manner that she takes care of the family, Mama is as committed to caring for the plant. Despite its bad surroundings, the plant thrives because she wants it to. This is comparable to the family's growth, which similarly prospers in spite of its challenging conditions.
