Flowers are generally divided into female and male, how should we distinguish between them?

In the middle of the female flower is a relatively large column, which is the part that bears fruit after pollination. There are several cores in the middle of the male flower, and the plush part at the top is pollen. When there are only stamens in a flower, we call it a male flower, only a pistil we call it a female flower, and a flower with both pistil and stamens is called a hermaphroditic flower, and the female flower and the male flower are collectively called unisexual flowers.

Dioecious: Males without ovary, such as walnuts, melons, etc. The striped inflorescences of chestnut are male flowers; The spike-like inflorescences of Ginkgo biloba are male flowers (dioecious), and many others are dioecious, such as Yueji (Rosaceae) and so on.

The main thing is to look at their stamens. There is a relatively large stamens in the middle of the lotus flower. The stamens of the male flowers have numerous hairs.

1. The position of the stamens is different.

The stamens of the female flower are located in the ** part of the flower, and it can produce plant egg cells.

The stamens of the male flowers are located in the corolla.

Inside, it produces pollen grains.

2. The structure is different.

Female flowers are usually composed of three parts: the ovary with the base enlarged into ascomycetes, the cylindrical columella at the upper part of the ovary, and the stigma with the enlarged stigma at the top of the columella.

The stamens of male flowers usually consist of filaments and sac-like anthers at the tips of the filaments.

Composition, the filaments are usually slender and filamentous, varying in length.

3. The functions are different.

The main function of female flowers is to receive pollen provided by male flowers, and after fertilization, they develop into fruits;

The main function of male flowers is to provide pollen for female flowers, which have only stamens and no pistils, and the flowers themselves do not have a chamber and cannot develop into fruits.

Female flower characteristics

The size of the female flower is expressed by the diameter of the flower (about twice the length of the petals), the size of the ovary (there are transverse and longitudinal diameters, but it is easy to indicate with a large variation in transverse diameter), and the number of columella (although it is usually 3 columella and 6 stigmas, there are also flowers with 4 stigma and 8 stigmas, and 2 columella and 4 stigma). Since the items are interrelated, it is generally better to take the big one.

From the point of view of the fullness of the ovary, the ratio of the transverse diameter of the ovary to the flower diameter is the best. When the eyes are continuous and the plant is full, the flower diameter is slightly smaller, but the ovary is plump and hypertrophied. The length and thickness of the flower are also related to the size of the flower, and the flower stalk is long and thick, and its flower is also large.

The above content reference: Encyclopedia - Female Flower.

Female flowers have a columella and no ovary, and male flowers have stamens and pollen without ovary. The pollen of the male flower is pollinated by wind or insect to the female flower column to complete fertilization.

Female flowers can produce fruit, while male flowers cannot, but female flowers are pollinated by male flowers to bear fruit.

The most common typical parthenogenesis plants are many varieties of the Cucurbitaceae family, such as pumpkin, gourd, cucumber, loofah, watermelon, etc.

As shown in the figure below (pumpkin flowers), the female flowers with the ovary on the top are the female flowers, and the male flowers without the ovary on the bottom side.

Many angiosperms have both female and male flowers.
