Structure And Function Of Flower Archives

Structure and Function Of Flower: Flower: Flowers are the reproductive part of flower plants. The flower is highly modified shoot responsible for the production of seed and fruit. The root stem and leaves are the different organ of the plant and the flower is meant for Flowers may produce individually on the plant, or they may develop together in any. also see Structure of Flowers: A flower is basically made up of four concentric rings of structures or floral leaves. Andorecium Calyx Gynoecium Corolla Arranged on Thalamus. Cohesion of Sepals: The Sepals may be united to each other partially or completely or free from one another. According to cohesion the calyx may be: Polysepalous: When these are free from each other . if we pull a sepal, the other are not pulled along with itGamosepalous: When sepals are combined to each other. If we will drag a sepal, all will be pull the flower expend.foe example in Rosa. Shape of Calyx: The fusion of sepals results in various shapes of the corolla. Such as: Tubular: The sepals are merg to form a tube-like makeup, e.g.; in Verbena. Campanulate: Shape of a calyx become a Bell-shaped, in Petunia alba. Infundibulum: Sepals unite to form and become funnel-like. Sepal unite and it become like of funnel. Pappus: The sepals are greatly compact and are represented by hairs forming a shape. In Sunflower Color of Sepals: The sepals are green usually, but in some cases they may be colored like petals. Such sepals are called Petaloid. Corolla: It is the second ring of flower inside to calyx. It comprises of colored floral leaves the Petals. Petals are together called corolla. Petals: The petals may be set in single whorl or many whorl. When petals are free from one another known as When all or few petals are united known as gamopetalous. Shape of Corolla: They may be occurs in many different shapes; Clawed Cruciform Bilabiate Tubular Position and Color of petals: Their position may be inferior and may be superior according to their position on thalamus. Structure and Function Of Flower is also discuses their. Androecium: Androecium is the first of two reproductive whorls of flower present next to corolla of flower. They comprises the stamen of flower. Stamen: Each stamen consists of filament, stalk, and also bilobed structure at the top of the filaments of flower. Anther: Anther lobes are joined with each other through a tissue. They are also with joined with pollens. These stamens are also called Number and length of stamens: Androecium may comprise of only two or more stamens of each flower. All these are present free from each other because of its length. The stamens of flower may be the same length. There may vary with relation to each other with flower. Stamens may be short or long in size. Position of the stamens on Thalamus: Stamens are inserted below the level of ovary this condition is called the When the stamens are inserted above the level of ovary this condition is known as the Gynoecium: Gynoecium is inner most whorl of flower consisting of the carpels. This occupies the center of thalamus usually this is called a Carpel: A carpels are considerd to be a modified folded leaf of the plants. two margin of the leaf fuse together of each plant. fused margin is usually called ventral suture of plant. the line related the midrib of leaf is maybe called the dorsal suture. also see
