What is Pollen Germination?
Pollen germination occurs when pollen grains fall on the stigma, develop into a tube, and penetrate the ovule. The pollen tube grows down the style, which joins the ovary and stigma and enters the ovule.
Pollen germination takes place in the following steps:
- Dust from the pollen falls on the stigma.
- Pollen grains stick to the stigma because of their sticky exterior.
- As pollen grains germinate, a tube is formed.
- A pollen tube descends the style towards the ovule.
- Germ cells enters the ovule

Pollen germination on the stigma is a crucial step in the sexual reproduction of flowering plants. It involves the deposition of pollen grains onto the stigma followed by the growth of pollen tubes, which eventually penetrate the stigma and deliver sperm cells to the ovule for fertilization. The pollen germination on stigma Class 12 practical is an important experiment in the biology syllabus.
Observing pollen germination on the stigma traditionally involves live microscopy techniques, which offer real-time insights. In this article, we will learn about the germination of pollen on a slide in the form of an experiment and the concept of pollen germination.
