We can define flowers as a set of modified leaves specialized in plant reproduction. The flowers have a structure usually formed by sterile parts (sepals and petals) and fertile parts (stamens and carpels).
To the set of sepals we give the name of chalice, and to the set of petals, corolla. The sepals are usually green, distinguishing them from the petals, which are often showy to attract pollinators. The sepals together with the petals form the so-called perianth.
In relation to the fertile parts, the set of stamens is called androceus, and the set of carpels, gynoecium. Stamens are structures formed by a filament (fillet) where the anther is attached, where the pollen grains are found. Carpels are structures where eggs are located.
Depending on the species, the flowers can appear isolated on a branch or in a inflorescences. we can define inflorescences like branches that have flowers. The inflorescences can be divided into two large groups, based on their development: the racemose and the cymoses.
Do not stop now... There's more after the advertising ;)
At racemose inflorescences are those that have a main axis that ends in a yolk and grows longer than the lateral branches. already the jealous have axes that end in a flower.
These two groups are divided into several other ways. See below the types of inflorescences and some illustrations:
Note the illustration of different types of inflorescences
Types of racemose inflorescence:
-Racemo;
-Corymb;
-Ear;
-Spadix;
-Chapter;
-Umbel;
-Panicle;
-Compound umbel;
Types of timorous inflorescences:
-Monocasium;
-Scorpioid;
- Helicoid;
-Ripidio;
-Dicasium;
-Pleocasium.
There are also some special types of inflorescence, as an example we can mention the spikelet, a inflorescence typical of the Poaceae family (Graminia), and sciathium, an inflorescence found in the family Euphorbiaceae.
