Labelled diagram of Longitudinal section of flower
Labelled diagram of Longitudinal section of flower: The reproductive parts are located in the flower. We have studies the different parts of flowers- sepals, petals, stamens and pistils. Stamens and pistils are the reproductive parts of flowers that contain the germ-cells.
Stamens or pistils or bisexual (hibiscus, mustard) A flower can be unisexual (Papaya, watermelon) when it has both stamens and pistils. The stamen is the male reproductive part and produces yellowish colored pollen.
You must have seen this yellowish powder that often sticks to your hands when you touch the stamens of the flower. The pistil is the centre of the flower and is the female reproductive part. It is made up of three parts.
The swollen lower part is the ovary, the elongated middle part is the style and the terminal part which may be sticky is the stigma. Ovaries contain ovules and each ovule contains an egg cell.
The male germ-cell produced from the pollen grains fuses with the female gamete in the ovule. This fusion or fertilization of the germ-cells gives us the zygote which is capable of growing into a new plant.
