True

Explanation:

Flower is the reproductive part of the plant life cycle. It has typically four parts named as sepal, stamen, petal and pistil.

Sepal is the basal leaf like part of the flower. The group of sepals forms the outer whorl of the flower. They are collectively named as calyx.

Petal is the part of flower above the sepal. The petals in flower are typically of bright color so as to attract pollinators. They are collectively termed as corolla.

Stamens are the filamentous structures of a flower. They form the male reproductive part over which anthers are present. Anthers carry pollen grains which are the male gametes.

Pistil forms the female reproductive part. It consists of style, stigma, and ovary.
