Petal − Petals are basically modified leaves that function to protect the reproductive parts of flower. Petals are bright in color to attract pollinators.

Pistil − Pistil is the female reproductive organ of flower. The pistil contains ovary in its swollen base. Ovary further contains ovules that take part in fertilization.

Sepal − Sepal is usually green in color, but is some flowers, it is of same color as of petals. The main function of sepal is to protect the flower when it is a bud.

Stamen − Stamen is the reproductive organ of the flower that produces pollen grains.

The table is completed as shown below:

Organ	Location	Function
Petal	Modified leaves that surround the reproductive organ of flower.	Petals protect the reproductive organ of flower.
Stamen	It is located between pistil and surrounding petals of flower.	Stamen produces pollen grains, that contain sex cell.
Sepal	Sepal is generally green in color and is found on the outermost part of flower.	They protect buds and reproductive organ of flower.
Pistil	It is located centrally in a flower.	Its main function is to produce ovule.
