Structure of a Flower

 
6.1 Structure of A Flower
 
Introduction to Flower
  • Flowers are the most distinctive organs in the angiosperms.
  • The beauty and scent of flowers which have evolved, not only attract animals and insects, but also play a role in ensuring the survival of species.
  • The flowers contain the plant reproductive structures.
  • Flowers contain both male and female reproductive organs.
  • Besides, flowers also have structures called peduncles, sepals and petals.
 
This image is a detailed diagram of a flower's reproductive parts. The flower is divided into male and female reproductive organs. The male part, labeled ‘Stamen,’ includes the anther and filament. The female part, labeled ‘Carpel,’ includes the stigma, style, ovary, and ovule. Other parts of the flower, such as the petal, sepal, and peduncle, are also labeled. The diagram uses arrows to point to each part for clarity.
 
Comparison between Male and Female Structures in a Flower
Similarities
The image shows a comparison between two items, labeled as ‘1’ and ‘2’. Both items are presented in separate boxes with light yellow backgrounds and light blue headers. 1. The first box states: ‘Both produce gametes.’ 2. The second box states: ‘Both are located at the flower's organ.’ The image also includes the logo ‘Pandai’ in the top left corner.
Differences
Male Flower Part Female Flower Part
Consists of stamen. Consists of carpel.
Has filament and anther. Has stigma, style and ovary.
Produces pollen grains. Produces embryo sac.
Projecting out from the base of the ovary. Located in the middle part of the flower.
 
The Number of Stamens
  • The number of stamens in a flower varies according to species.
  • The rosary pea has a single stamen.
  • The saguaro cactus in the Sonoran Desert, Arizona has the highest number of stamens, that is, 3482 stamens in a single flower.
