Answer 1

The correct option is A Every flower has all the four parts (sepals, petals, stamens and pistils) present.

• The four main parts of the flower that may or may not be present in the same flower are sepal, petal, stamen, and pistil.
• Sepal: They are green leaf-like structures that help in the protection of flower in its bud stage.
• Petal: They are the most attractive and brightly coloured part of the flower.
• Stamen: It is the male reproductive organ of a flower. It consists of anther and filament. Anther produces pollen grains which is the male gamete. The arrangement of anther and filament varies in different stamen. Therefore, different flowers have different stamens.
• Pistil: It is the female reproductive organ of a flower. It has three parts i.e., stigma, style and ovary. Inside the ovary, there are bead-like structures called the ovules which are the female gametes.
