What is the function of the sepals in a flower?
The sepals are an important part of the development of the flowers of angiosperms or flowering plants. Their main function is to protect the flower bud as it develops . The sepals on a flower, collectively known as the calyx of the flower, are the first layer of a flower bud to form on the stem. The calyx of sepals, as the outside layer, forms a protective enclosure for the inner flower tissues (petals and the male and female parts) to form. Once the flower has bloomed, the sepals usually whither and lose their importance, though on some species they can also protect the seed.
What is the role of sepals in plants?
Sepals are protective structures found on almost every flowering plant on earth. The flowering plants, or angiosperms as they are scientifically known, are the most common group of plants on land. Since these plants reproduce with their flowers, producing a healthy flower is extremely important. This is where the role of the sepal comes in.
What happens when a plum flower matures?
When mature, the petals and reproductive structures cause the bud to swell. The inner flower parts push through the calyx separating the sepals allowing the flower to bloom. The petals advertise that the plant is ready for reproduction, and the male and female parts will combine to make the seed. At this point in many angiosperms, the sepals' job is mostly complete. The photo of plum blossoms below shows the various stages of the flower buds' development. In this species, the sepals are not green and appear before the leaves do.
How many sepals does angiosperm have?
Different groups of angiosperms will have different numbers of sepals and petals. Typically, the angiosperm group of monocots has sepals in multiples of 3 and the dicot group will have them in multiples of 4 or 5. Sepals, like flowers, can come in different shapes and colors depending on the species, but their main function is the same, They protect the bud so a healthy flower can bloom.
What are the leaves on a poppy?
Sepals are modified leaves that encase or cover a flower bud as it develops. Sepals protect the delicate and intricate flower structures inside from drying out and being damaged by outside elements (rain, insects, etc.) until they mature. Sepals are the outer layer of the flower structure and are the first part of the bud to show up. As the flower matures and the bud swells, the sepals open, and the petals and reproductive structures inside bloom forth. The picture of the poppy bud below shows the fuzzy, protective sepals opening up to reveal the colorful petals inside.
What protects the petals and reproductive structures as buds form on the stem?
The sepals protect the petals and reproductive structures as buds form on the stem.
How do bud flowers form?
The bud will begin its formation starting with the outside layer first, the calyx. The calyx, made of sepals, will form its protective envelope. Then within this enclosed outer whorl of the bud, the inner whorls will develop. First, the petals will form, followed by the male reproductive structures called stamens, and, finally, the central female reproductive structures called carpels. The flower diagram above shows the location of these structures on a generic flower.

These are small modified leaves , with a rough texture and herbaceous appearance, which are found between the stem and the petals, acting as the outermost envelope of the floral calyx.
What function do flower sepals have?
What are flower sepals for ? The main function of the sepals occurs during the flower formation process . The main task of the sepals is to protect the reproductive organs of the flower in these early stages.
Types of sepals
We can classify the sepals of the flowers into several groups according to their characteristics:
Other parts of the flowers
In addition to the sepals, there are other well-differentiated parts of the flowers that you can easily observe if you stop to take a look.
What is the function of sepals in flowers?
Sepals is modified leaves (just like petals). The function of sepals is to protect the flower from buds and insects. The number of sepals in a flower is a trustful indicator of its merosity (plant's classification indicator). Some sepals dry and die after flowering, but some retain as a protection for the seed or fruit.

Why are the petals green?
They are used green in colour because they contains chlorophyll molecules which Trap light energy for photosynthesis. They protect the flowers during the buds stage.
What is the first step in the production of flowers?
The first step in the production of flower is the formation of sepals. They form a tightly closed area called as bud. Flower is formed inside the bud which contains petals and reproductive parts. During the production of flower, the sepals form a protective enclosure for the flowers keeping it from drying out.
