Difference between Anther and Stigma

A flower consists of male and female reproductive parts. The male reproductive part, also known as the androecium, is made up of anther and a filament. The female reproductive part, also known as the gynoecium, is made up of stigma, style and an ovary.

However, both the male and female structures differ in their structures and functions entirely. Let us look at the difference between anther and stigma in the table below:

Anther

Stigma

Description

Anthers are the male reproductive part of a flower.

Stigma is the female reproductive part of a flower.

Structure

The anthers are bilobed with sac-like structures (microsporangia) present inside them.

The stigma is a receptive base on which the pollen lands.

Function

It is inside the sac-like structures that the pollen is produced.

The base/tip of stigma is responsible for the reception of pollen grains.

Frequently Asked Questions

What is the difference between anther and pollen?

The anther is the bilobed structure of stamen in which pollen is produced, whereas pollen is a grainy powder-like substance that is produced in flowers and is the male gamete.

What will happen if the anther or stigma of the flower is missing?

If anther or stigma of a flower is missing, then the flower can cross-pollinate. Cross-pollination is the fertilisation of pollen from one flower with the stigma of another flower, either in the same plant or another plant of the same species.

Why are anthers positioned and where they are?

The anthers are positioned at the top of the flower so that they are accessible to the pollinators for pollination.
