In a flower, pollen tube enters through pistil into ovule. Name the parts of pistil.

Explanation

### Step-by-Step Solution:

1. **Identify the Pistil**: The pistil is the female reproductive part of a flower, which is responsible for the reproduction process.

2. **Parts of the Pistil**: The pistil consists of three main parts:
- **Stigma**: This is the top part of the pistil where pollen grains land. It is often sticky to facilitate the adherence of pollen.
- **Style**: This is the tube-like structure that connects the stigma to the ovary. It serves as a pathway for the pollen tube to travel from the stigma to the ovary.
- **Ovary**: This is the swollen base of the pistil that contains the ovules (egg cells). The ovary is where fertilization occurs when the pollen tube reaches the ovule.
