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.

    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.

    I hope this information is helpful. If you need a table with different features or more information, please let me know.
