The style is the part of the pistil which leads to the formation of the pollen tube.
Stigma is the part of the pistil which holds the pollen.
Stamen is the male reproductive part of the flower which is made up of two parts the filament which is a stalk that attaches to anther bilobed structure that forms pollen grains.
The ovary is the main female part that leads to the formation of an ovum.

  1. Pistil and stamen

  2. Ovary and anther

  3. Pistil and ovule

  4. Ovary and stamen

Show answer
Correct Option: A
Explanation:

Stamen or androecium are the male reproductive part and responsible for the production of pollen grains (male gamete). Pistil or gynoecium are the female reproductive part and produce ovum (female gamete). If both the organs are present it is called bisexual flower. If one of them is present the flower is referred to as unisexual.
So the correct option is 'Pistil and stamen'.
