What is the difference between the bracts and sepals of plants?

The sepals are in the outermost part of the flower, which is the first round of the flower and plays a protective role in the flower. The shape is generally similar to that of a leaf, usually green, and it is capable of photosynthesis. The bracts are composed of a number of petals, which are the second round of the flower, which has a protective effect, and the cells contain anthocyanins or chromosomes, so they have bright colors, can secrete volatile substances, and release aromatic odors.

The bracts and sepals refer to the components of the flower, and in the flowers of plants, the petals have two types of nucleus: bracts and sepals. The bracts and sepals have one thing in common, that is, they are both external structures of the flower that rise around the flower.

However, they also have some differences, which are detailed below.

From a morphological point of view, there are three major differences between bracts and sepals. First of all, bracts differ from sepals in their petals. The petals are often eye-catching, colourful parts that work together to act as a protective attraction to pollinators such as insects.

The bracts of the flower are protected by the rigid germ formed by the initial stage of the flower. Secondly, the sepals cling to the inner layer of the flower bud, while the bracts are mostly on the outer layer of the flower. Finally, there are also differences in the growth position of bracts and sepals.

The bracts are usually located at the base of the flower, while the sepals are located at the base of the petals. This makes the bracts and sepals distinct in appearance.

In the reproductive process of plants, the bracts and sepals of flowers also play an important role. The bracts are often able to attract pollinators, which in turn helps the flowers to pollinate. Sometimes, the bracts will be more showy in color than the petals and are more easily recognizable by pollinators.

Sepals play a relatively small role in attracting pollinators, and their primary responsibility is to protect flower buds. When the buds are ready to open, the sepals will, opening the way for the petals and acting like petals.

In conclusion, the bracts and sepals, although they differ in the appearance and function of the flower, are very closely related to each other and together form the external structure of the flower. By understanding the difference between bracts and sepals, we can gain insight into the morphological structure, ecology, and reproductive processes of plants. <>

Corolla. The sepal is a plant tissue that refers to the outermost part of the flower and protects the inner part of the flower bud. A complete sepal makes up the calyx.

It is often green. The sepals separated from each other are called sepals, the sepals are called rotten sepals, the lower end of the sepals is called the sepal tube, and the upper part of the sepals is called the sepal lobe; The outer wheel of the two-wheel sepal lobes is called the secondary calyx, such as the large red flower and other mallows.

Hello, the sepals are closest to the vegetative tissue of the plant onslaught. The calyx is located on the outermost wheel of the flower, is generally green, and consists of sepals. The structure of the sepals is similar to that of the leaves.

The upper and lower epidermis are made up of a layer of cells, and sometimes stomata and various hairs can be seen. The upper and lower epidermis is composed of multiple layers of parenchyma cells, with little differentiation of palisade tissue and spongy tissue, often containing chloroplasts and becoming green. In parenchyma there is a distribution of vascular bundles.

Some medium-grinding plants also have oil cells, mucus cavities, stone cells, calcium oxalate crystals, etc.
