Pollen Tube Journey: How it Reaches the Ovary - Plant Reproduction Explained

The pollen tube reaches the ovary through the style. The style is a long, slender structure that connects the stigma to the ovary. The stigma is the receptive surface of the flower that receives the pollen grains. When a pollen grain lands on the stigma, it germinates and produces a pollen tube. The pollen tube grows through the style and into the ovary. The ovary contains the ovules, which are the female gametes of the flower. The pollen tube fertilizes the ovules, which then develop into seeds.
