Hii guys 🤩
The morphology of the flower,or its shape and structure can be seen in two parts. A nutritional part consisting of non reproductive structure such as petals. And the reproductive or sexual part. Stereotyped flowers consists of four types of structure called receptacles which are attached to the top of short steam or shafts. Each of these parts are the organs of the flowers are arranged in a spiral called a swirl. The four major vertebrae ( starting at the base of the flower the lowest node and extending upward)are the calyx , corolla, stamens and pistil. The corolla and corolla together form a non reproductive part of the flower called perianth which in the some case in indistinguishable. In this case, they are called tepals.
Perianth
Main article: perianth

Sepals, collectively referred to as sepals are the modified leaves found in the outermost swirls of flowers. They are like leaves in that they have wide bases,stomata , stems and chlorophyll. Sepals are often waxy and tough and grew rapidly to protect the flower as they grow. They can be deciduous, but more often they continue to grow to support fruit dispersal. When the Goku fuses it is called Gamosepal.

The petals together with the corolla are almost completely fibrous leaf luke structure that from the inner most swirl of the perianth. They are often delicate and then usually colored, shaped,or scented to promote pollination. Its shape resembles a leaf but it resembles a stamens in that it forms at about the same time, but its subsequent growth is delayed.
Androceo
Androecium or stamens are the rings of pollen that from the male part. Anthers usually consist of a single anther which is connected to a filament or stem by four anther. Pollen contains microsporocytes which after miosis become male gametophytes amd become pollen. Although they should a wide variety between flowering organs the androecium is usually limited to one ring and rearly to two rings. Stamens differ in number, size, shape, Orientation and point of attachment of the flower.
Gynecologist
The gynoecium or stamens are the female parts located in the inner ring of the flower. Each carpel has a stigma that receives the pollen a pistils that acts as a steam and an ovary that contains the eggs. Stamens can consists one or more coils and when joined together are often described as pistils. Inside the ovary the eggs are suspended on a piece of tissue called the placenta.
