⭕Receptacle: It is a base of a flower above the flower stem. It is at receptacle that all other parts of a flower are attached.

⭕Sepals: These are the green leaf-like parts which are present on the outer most part of the flower. Sepals help in protecting the flower when it is in the form of a bud. All sepals of a flower together are called calyx.

⭕Petals: Petals are the colourful leaves of a flower. All the leaves of a flower together are called corolla. The petals of a flower have fragrance and they attract insects for pollination. Their function is to protect the reproductive organs present in the centre of a flower.

⭕Stamen: Stamens are the male reproductive organ of a plant. They are present inside the ring of petals and are little stalk with swollen tops. Stamen is made of two parts, anther and filament. The stalk of stamen is called filament and swollen top is called an anther. The anther of a stamen produced pollen grains and stores them. These pollen grains contain male gametes of the plant. A flower has a lot of stamens in it.

⭕Carpel: Carpel is the female reproductive organ and is present in the centre of a plant. The shape of carpel is like a flask. Carpel is made of three parts, stigma, style and ovary. The top part of carpel is called stigma. The stigma is sticky and receives pollen from anther of stamen. The pollen grains sticks to the stigma. The centre part of carpel is called style. Style is a tube which connects stigma to ovary.
