Key Insights

  • 🕵️‍♂️ The stamen is the male reproductive part of a flower and consists of the filament and anther.
  • 😃 The anther is a bi-lobed structure that contains pollen sacks, which store pollen grains.
  • 🕵️‍♀️ The carpel is the female reproductive part of a flower and consists of the style, ovary, and stigma.
  • 🕵️‍♀️ The ovary contains ovules, which enclose the female gametes.
  • 🧑‍🏭 The style connects the ovary to the stigma, which acts as the receptive surface for pollen grains.
  • 🕵️‍♀️ Pollen grains are the male gametes and are responsible for fertilizing the female gametes.
  • 🌱 The stamen and carpel are crucial for the process of reproduction in plants.

Questions & Answers

Q: What are the main parts of the stamen?

The stamen consists of the filament and the anther. The filament is a stock that bears the anthers.

Q: What is the function of the anther?

The anther is responsible for producing and storing pollen grains, which contain the male gametes.

Q: Where are the pollen grains stored in the stamen?

The pollen grains are stored inside the pollen sacks, which are located in the lobes of the anther.

Q: What are the main parts of the carpel?

The carpel consists of the style, ovary, and stigma. The style connects the ovary to the stigma.

Summary & Key Takeaways

  • The stamen, the male reproductive part of a flower, consists of the filament (a stock that bears anthers) and the anthers (bi-lobed structures containing pollen sacks).

  • The pollen sacks in the anthers store pollen grains, which contain the male gametes responsible for reproduction.

  • The carpel, the female reproductive part of a flower, consists of the style (a tube-like structure connecting the ovary and stigma), the ovary (containing ovules where female gametes are located), and the stigma (the receptive surface for pollen grains).
