Which structure holds up the stigma and allows the pollen tube to grow toward the ovum?

The style is the structure that supports the stigma and facilitates the growth of the pollen tube toward the ovum. In flowering plants, the stigma is the receptive tip of the pistil where pollen grains land and germinate. The style connects the stigma to the ovary, which contains the ovules. When pollen lands on the stigma, the pollen tube begins to grow down through the style to reach the ovary, where fertilization can occur. The style serves as a conduit, ensuring that the pollen tube can successfully navigate to the ovum for fertilization to take place. This structural arrangement is essential in the reproductive process of angiosperms, enabling efficient transfer of male gametes to female gametes.
