Q.14.What is the main function of a flower? Name the main parts of a flower.

Ans. The flowers are the reproductive part of a plant because they contain reproductive organs. The main function of flowers is to produce fruits and seeds. The main parts of a flower are: Sepals, Petals, Stamen and Pistil.

Q.15. Describe the structure of a flower.

Ans. The green, leaf-like parts in the outermost circle of a flower are called sepals. The sepals protect the flower when it is in the form of a bud in the initial stage.

Petals are the most attractive part of a flower, these can be of different colours, shapes and sizes. petals of some flowers have natural scents in them due to which they smell very nice and attracts insects etc. The rings of colourful petals in a flower protects the reproductive organs (stamen and pistil) of the flower.   

In plants like china rose, if we remove the petals we can see  the stamen inside. stamen is the male part of the flower. Each stamen consists of  hair like structure called the filament and a lobed bag like structure called the anther at the tip of the filament. The anther contains dust like particles called the pollen grains.  The pollen grains contain male sex cells .

The innermost flask-shaped part of the flower is called the pistil (carpel). It is the female part of the flower. It consists of a small sticky disc-like structure called the stigma on the top. stigma runs into a long tube-like structure called the style and a swollen base called the ovary. Ovary has a number of small bead-like structures called the ovules. The ovules contain female sex cells.
