REPRODUCTIVE PART OF BISEXUAL FLOWER CBSE BIOLOGY

 

1. Stamens – The male reproductive part

• Structure: A stamen is typically made of two main parts:

  • Anther: The oval-shaped structure at the tip that produces pollen grains (the male gametes). Each anther usually has two lobes, and inside each lobe are pollen sacs containing microspores that develop into pollen.

  • Filament: A slender stalk that supports the anther and positions it so that pollinators or the wind can easily carry away the pollen.

• Function: Produces and releases pollen, which contains sperm cells for fertilization.

2. Carpels (or Pistil) – The female reproductive part

• Structure: A carpel consists of three main parts:

  • Stigma: The sticky top surface that receives pollen grains during pollination.

  • Style: A tube-like structure connecting the stigma to the ovary; it allows pollen tubes to grow down toward the ovules.

  • Ovary: The swollen base that contains ovules; each ovule contains a female gamete (egg cell).

• Function: Receives pollen, enables fertilization, and develops seeds and fruit after fertilization.
