The pollen grains germinate on the stigma and resulting in `"___________"` formation which grows through the `"___________"`.

Options

A. Pollen tube, style
B. Male gamete, ovary
C. Vegetative cell, style
D. Tube cell , stigma

Answer

To answer the question, we need to fill in the blanks regarding the process of pollen grain germination and the subsequent formation that occurs.

1. **Understanding Pollen Grain Germination**: Pollen grains are the male gametes in flowering plants. When they land on the stigma, they germinate. This process involves the pollen grain developing a structure that allows it to grow towards the ovule.

2. **Formation Resulting from Germination**: Upon germination on the stigma, the pollen grain forms a **pollen tube**. This tube is essential for the transport of male gametes to the female gametophyte located within the ovary.

3. **Pathway of Growth**: The pollen tube grows through the **style**, which is the elongated part of the pistil that connects the stigma to the ovary. The style serves as a conduit for the pollen tube to reach the ovary where fertilization occurs.

4. **Final Answer**: Therefore, the completed sentence is: "The pollen grains germinate on the stigma and resulting in **pollen tube** formation which grows through the **style**."
