What is the Difference Between Anther and Stigma?
🆚 Go to Comparative Table 🆚The main difference between an anther and a stigma lies in their roles in the reproduction process of a flower. The anther is part of the male reproductive system, while the stigma is part of the female reproductive system.
Anther:
- Anthers are the male reproductive part of a flower, located inside the sac-like structures (microsporangia).
- They are responsible for producing pollen, which contains the male gametes.
- The anther is part of the stamen, which also includes a filament that holds the anther up.
Stigma:
- The stigma is the female reproductive part of a flower, located at the top of the pistil.
- It is a sticky structure where pollen lands and germinates.
- The stigma is connected to the style, a long, tube-like structure that leads to the ovary, which contains the female egg cells called ovules.
In summary, anthers produce pollen grains, while stigmas receive pollen grains for fertilization.
Comparative Table: Anther vs Stigma
I understand that you want a table comparing the differences between an anther and a stigma. However, the search results provided are not relevant to the topic, as they focus on social stigma and other unrelated concepts. I will provide a comparison between an anther and a stigma based on my existing knowledge.
Feature | Anther | Stigma |
---|---|---|
Definition | The anther is the part of a flower that produces pollen, which contains the male reproductive cells of a plant. | The stigma is the part of a flower that receives pollen, often sticky or hairy to trap pollen grains. |
Function | The anther's primary function is to produce and release pollen, which contains the male gametes (reproductive cells) of a plant. | The stigma's primary function is to receive pollen, which then germinates and forms a pollen tube that grows through the style to reach the ovary. |
Location | The anther is located within the flower, typically inside the petals. | The stigma is located at the end of the style, which is part of the pistil, the female reproductive organ of a flower. |
Structure | The anther is composed of one or more pollen sacs, where pollen is produced and stored. | The stigma is often sticky or hairy in texture to trap and hold pollen grains. |
