Answer 1

The flower is the prettiest part of a plant that mainly acts as an organ of reproduction i.e. it is the reproductive part of the angiosperms. There are two types of reproductive parts present in a flower which are the male reproductive part and the female reproductive part.

Complete answer:
The flower is one of the most important parts of a flower. Its characteristic structure is concerned with sexual reproduction in angiosperms or flowering plants i.e. flowers are the main reproductive part of the angiosperms. A complete flower consists of different parts.
In a complete flower, it holds a calyx of outer sepals and a corolla of inner petals. The sepals and petals together build the structure that is known as the perianth. In the inwards of the flowers, there are a number of stamens present. These stamens produce pollen grains, which is the main component of fertilization. Each stamen contains a microscopic male gametophyte. The stamens are known as the male reproductive part of a flower which collectively generates the androecium. And in the middle of the flowers, there are carpels present. It contains one or more ovules. Within each ovule, there is a tiny female gametophyte found. This carpel of the flower is known as the female reproductive parts of a flower which collectively form the gynoecium.
According to the presence of the reproductive part, the flower can be categorized into two distinct groups. One of them is unisexual while the other one is bisexual.
When in a flower, there are both reproductive organs i.e. male and female present which then the flowers are known as full or bisexual flowers. Generally, self-pollination takes place in this type of flower. Tulip, sunflower, lily, daffodils, mustard, and hibiscus are some examples of bisexual flowers.

Hence, the correct answer is option (A).

Additional information:
When in a flower, there are any one of the two reproductive parts i.e. either only the male or female reproductive organs present then the flower is called unisexual flowers. To reproduce a new plant, this type of flower goes through the process of cross-pollination. Papaya, white mulberry, and watermelon Are the example of a unisexual flower.

Note: Flowers are the reproductive organ in a plant. Generally, there are two types of reproductive parts present in the flowers; male and female reproductive parts. When a flower bears either male or female reproductive part then the flower will be called unisexual and as opposed to when a flower bears both male and female reproductive parts then the flower will be called bisexual.
