2) Pollen tube is hollow, long tube like structure developed from intine of pollen grain whereas style is elongated hollow or solid structure made of soft tissues
3) Pollen tube carry male gametes and grow inside style, reach to the ovary, penetrating it and release the male gametes inside whereas style make connection between stigma and ovary and provide safe path for growth of pollen tube inside
4) Pollen tube grow inside style of female gametophyte whereas style do not grow inside Pollen tube
5) growth of pollen tube is stimulated by sugary substances produced in stigma whereas style do not need to grow, it is already part of female gametophyte.
