The diagram shows style and stigma i.e. female flowers, but actually tassels are male flowers.
I think it's wrong in the ncert

Answer:

Part of the Flower Represented by Tassels of Corn-Cob:

The tassels of a corn-cob represent the male reproductive part of the corn plant, i.e., the staminate flowers.

Explanation with Diagram:

The corn plant is a monocotyledonous angiosperm that belongs to the grass family. The corn plant has separate male and female flowers, and each corn plant has both types of flowers. The tassels of the corn-cob represent the male flowers, while the kernels or seeds represent the female flowers.

The staminate flowers of the corn plant are located on the tassels, which emerge from the top of the corn plant. Each tassel contains many flowers, and each flower consists of a filament and an anther. The anther contains pollen grains, which are the male gametes.

When the corn plant is mature, the tassels release the pollen into the air, and the pollen is carried by the wind to the female flowers, which are located on the ear of corn. The female flowers consist of a stigma, style, and ovary. The stigma is sticky and captures the pollen grains that land on it. The pollen grain germinates on the stigma, and the male gamete travels down the style to the ovary, where it fertilizes the female gamete.

The fertilized ovary develops into a kernel, which is the fruit of the corn plant. The kernel contains the embryo and the endosperm, which provide nutrition to the developing corn plant.

Conclusion:

The tassels of the corn-cob represent the male reproductive part of the corn plant, i.e., the staminate flowers. The male flowers contain the anthers, which produce pollen grains that are carried by the wind to the female flowers, where they fertilize the female gamete and develop into kernels.
