Types of pollination[ edit ] Main article: Anemophily Wind-pollinated flowers often have small, dull petals and produce little or no scent.
They are divided into the following types. Now, we will look at the various parts of flowers in greater details. Anther: The pollen-bearing body of the stamenusually relatively compact, and supported at the end of the narrow filament.
Many flowers are symmetrical in only one plane i. Practice Question If the anther is missing, what type of reproductive structure will the flower be unable to produce?
These are known as tepals. Such patterns often function as guides to pollinators, and are variously known as nectar guides , pollen guides, and floral guides. The carpel is the individual unit of the gynoecium and has a stigma, style, and ovary. A flower may have exclusively male parts, exclusively female parts, or commonly, both. As a result, botanical nomenclature has been undergoing a bit of a revolution in the last two decades, and the process as of is still ongoing. These four parts are called calyx, corolla, androecium, and gynoecium. A flower may be trimerous, tetramerous or pentamerous when the floral appendages are in multiple of 3, 4 or 5, respectively. Solved Examples for You Q: Mention the different types of flowers. Function Moreover, the calyx protects the inner structures of the flower bud while the corolla attracts pollinators to the flower. Different flowers have different sizes and shapes of blades.
They surround the reproductive structures of the flower: stamen and pistil. In some plants such as Narcissus the lower part of the petals or tepals are fused to form a floral cup hypanthium above the ovary, and from which the petals proper extend.
Calyx corolla androecium gynoecium
Individual flowers are often organized into a larger group or cluster, termed an inflorescence. If all four whorls the calyx, corolla, androecium, and gynoecium are present, the flower is described as complete. Moreover, the sepals and petals of some flowers have the same color and size, making them indistinguishable from each other. More recently, genetic studies have been employed to determine the relationship of various botanical groups to each other. However, both calyx and corolla collectively form the perianth of the flower. The main difference between the calyx and corolla is their structure and function. The whorl of petals occurs inside the calyx and it protects the reproductive structures of the flower, including the stamen and pistil.
Many parts of the old classification system have proven more or less consistent with these studies, but there have also been a large number of changes, even to large and well studied groups.
The main difference between the calyx and corolla is their structure and function.
The number of petals in a flower may hold clues to a plant's classification. Examples include China rose.
