sepal, any of the outer parts of a flower that enclose and protect the unopened flower bud. The sepals on a flower are collectively referred to as the calyx. They are sterile floral parts and may be either green or leaflike or composed of petal -like tissue. The number of sepals in a flower is its merosity. Flower merosity is indicative of a plant's classification. The merosity of a eudicot flower is typically four or five. The merosity of a monocot or palaeodicot flower is three, or a multiple of three. The development and form of the sepals vary considerably among flowering plants. [13]
Sepals The Daily Garden
It is found on the outermost part of the flower, and like a petal, a sepal is considered to be a modified leaf. However, sepals are more likely to be confused with leaves since they are typically, but not always, green. Biology Biology Article Sepals Sepals Sepals are small, leaf-shaped, green-coloured and outermost part of the flower. They are the vegetative part of a flower, which functions by protecting the rising buds and by supporting the petals when in bloom. The sepals are considered as the modified leaves. Frequently Asked Questions What is the function of the sepal and petals? Sepals are considered part of the flower. They are the structure that covers a flower bud, protecting it as it. Sepal: The outer parts of the flower (often green and leaf-like) that enclose a developing bud. Petal: The parts of a flower that are often conspicuously colored. Stamen: The pollen producing part of a flower, usually with a slender filament supporting the anther. Anther: The part of the stamen where pollen is produced.

Whorls. Flowers are composed of sets of highly modified leaves arranged in whorls. The outermost whorl of a flower is called the calyx and is composed of sepals.Inside the calyx is the corolla, which is composed of petals.The sepals are often smaller and less colorful than the petals, but this general rule can be misleading. They are found below the petals . The sepals are often small and green. Some flowers do not have petals. Then the sepals may be big and colorful. In some flowers, the petals and sepals look the same. They are both called tepals . All the sepals together are called calyx . The number of sepals is different for different flowers. The sepals, collectively called the calyx, help to protect the unopened bud. The second whorl is comprised of petals—usually, brightly colored—collectively called the corolla. The number of sepals and petals varies depending on whether the plant is a monocot or dicot. Sepals are considered to be modified leaves with a simpler structure. They are usually green and often hairy but in some plants, e.g. monk's hood, they may be brightly coloured. sepal, a modified leaf, part of the outermost of the four groups of flower [1] parts. The sepals of a flower are collectively called the calyx and act as a protective.

Botanically, a flower is considered to be complete flower if it contains the four main parts of a flower: petals, sepals, stamen, and carpel (also known as a pistil). If a flower lacks any one of these parts, it is an incomplete flower. Rose, hibiscus and tulip are complete flowers because they have all the main flower organs. Key Terms. sepal: a part of an angiosperm, and one of the component parts of the calyx; collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower; corolla: an outermost-but-one whorl of a flower, composed of petals, when it is not the same in appearance as the outermost whorl (the calyx); it usually comprises the petal, which may be fused
In some flowers, the sepals may be fused along their margins or have deep crevices that create a more interesting appearance. Variations in size, shape, and color: The size, shape, and color of sepals vary greatly depending on the type of flower. In some flowers, the sepals may be small and barely visible, while in others, they may be large and. Sepals are small, leaf-shaped structures, forming the outer whorl of a flower. They are modified leaves, primarily green but can be of other colors too. Their number, size, and shape vary depending on the flower species. Sepals are either fused or separated. The sepals of a single flower are collectively called the calyx.
Glossary Tip Sepal
At maturity, the sepal opens when the flower blooms. The outer sepal epidermis (see Fig. 1) contains a characteristic pattern of diverse cell sizes ranging from giant cells one-fifth the length of the sepal to small cells one-hundredth the length of the sepal (Roeder et al., 2010). A sepal is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom. The term sepalum was coined by Noël Martin Joseph de Necker in 1790, and derived from the Greek σκέπη ( skepē ), a covering.
