The common characteristics of the fruits are and .

The common characteristics of the fruits are both (peel) and (seeds).

Hello, this question is very esoteric and not so simple. First of all, the common characteristics of fruits should be started from several aspects. 1. Look for it from the appearance.

2. Look for it from the inside. When we talk about the common characteristics of fruits, we mean that fruits have characteristics that are not found in other types of objects, such as having skin, fruit stalks, being able to eat, etc., are they unique characteristics of fruits? The answer is no.

Since I can't find the common characteristics of the fruit in the shape of the fruit, I can only look for the common characteristics of the fruit from the inside. It can be concluded that the fruit has both a peel and a seed.

In other words, all fruits have a two-part structure, and everything with a two-part structure, the skin and seeds, is a fruit.

The common feature of the fruit is that it is made up of the peel and the seeds.

The fruit is an organ in which the pistil of angiosperms is fertilized by pollination and developed with the participation of the ovary or other parts of the flower (such as receptacles, sepals, etc.). The fruit generally consists of two parts: the pericarp and the seed, among which, the pericarp can be divided into exocarp, mesocarp and endocarp. Seeds play a role in dispersal and reproduction.

The fruit is extremely closely related to human life. The vast majority of human food is the fruit of grasses, such as wheat, rice, and corn. Fruits commonly eaten by people, including apples, peaches, citrus and grapes, are rich in glucose, fructose and sucrose, as well as various inorganic salts, vitamins and other nutrients.

These fruits are not only delicious to eat, but can also be processed into a variety of foods such as dried fruits, jams, preserves, fruit wines, fruit juices and fruit vinegars. In addition, among the Chinese folk medicinal materials, fruits such as jujube, fennel, papaya, citrus, hawthorn, apricot and longan are commonly used in medicine.

The fruit is the organ of the angiosperm pistil that has been pollinated and fertilized, and is formed by the ovary or other parts of the flower (such as receptacles, calyxes, etc.). The fruit generally consists of two parts: the pericarp and the seed, among which, the pericarp can be divided into exocarp, mesocarp and endocarp.

Physiological and biochemical changes.

In the process of fruit growth and development, in addition to morphological and structural changes, it is also accompanied by complex physiological and biochemical changes, among which the changes of fleshy fruits are particularly obvious. For example:

Color: Fruit color is one of the important markers of fruit quality identification, and its color is related to the pigment contained in the peel. The main pigments are chlorophyll, carotenoids, anthocyanins, etc.

Texture: With the ripening process of the fruit, the texture of the peel gradually changes from hard to soft, mainly because the soluble pectin in the cell wall of the peel increases, and the protopectin decreases, so that the binding force between cells is lost, so that the cells are dispersed and the flesh is soft.

Aroma: During the ripening process of the fruit, some fruit aromas are produced, the main components include aliphatic and aromatic esters, and some aldehydes.

Sugars: starches that accumulate in the fruit, which are gradually hydrolyzed during ripening, are converted into soluble sugars, which sweeten the fruit.

Organic Acid Friendly Cavity: Contains a variety of organic acids in unripe fruits, which give the fruit a sour taste.

Tannins: When fruits such as persimmons and plums are not ripe, they have an astringent taste because the cell fluid contains more tannin substances.

Common characteristics of fruits include: vegetative organization, seed protection, seed dispersal, ripening indications, etc.

1. Nutritional tissue: Fruits usually contain one or more types of nutritional tissues, which are used to provide energy and nutrients to the developing seeds. These tissues can be pulp, precarp, seed coat, etc.

2. Seed protection: The fruit plays an important role in protecting the seed, and can form a protective barrier through the outer layer of the peel, husk and other substances to prevent the seed from being damaged and disturbed by the external environment.

3. Seed dispersal: The fruit also has the function of promoting seed dispersal. They may spread their seeds farther away through a variety of means, such as wind dispersion, water dispersion, and excretion after eating by animals, increasing the chances of plant reproduction.

4. Ripening indication: The ripening of the fruit can usually be judged by some characteristics, such as the change of color, the size and shape of the fruit, etc. These traits help attract eaters or other forces that promote seed dispersal.

In conclusion, the actual morphology and structure of the fruits of different plants can vary greatly, and these characteristics are just some of the common characteristics that are universal. Understanding the fruit characteristics of different plants can help us better understand the life history and reproductive strategies of plants.

The formation of fruit generally goes through the following stages

1. Pollination: In the flower part of the plant, pollen particles are transmitted to the pistils of the flowers through pollinators, wind or water. Pollen particles germinate on the stigma of the flower and grow through the pollen tube and eventually enter the ovary of the flower.

2. Pollinator sac development: In the ovary, the pollen tube combines with the ovule structure in the ovary to form a pollinator sac. The sperm cells in the pollination sac combine with the egg cell to complete the pollination fertilization process.

3. After fertilization, the fertilized egg develops into an ovule, and the endosperm cells in the ovule begin to develop.

4. Fruit formation: With the development of fertilized eggs and endosperm, the ovary of the flower gradually expands to form fruit, and at the same time, the ovary wall develops into the pericarp.

5. Seed development: The ovules inside the fruit develop into seeds.

6. Ripening and dispersing: The fruit goes through a certain stage of development and finally matures.

The common feature of the fruits is that they all have peels and seeds.

The fruit generally consists of two parts: the pericarp and the seed, among which the pericarp can be divided into exocarp, mesocarp and endocarp. The common characteristics of the fruits are that they all have peels and seeds, the ovary of the flower is born into fruit, the ovule develops into seeds, and the fertilized egg develops into embryos.

<> fruit of the plant, the fruit is a reproductive organ unique to the seed plant, which is formed by the rapid growth and development of the ovary of the pistil or some part of the early brother connected to it outside the ovary after pollination and fertilization. The ovary wall develops into a pericarp and is divided into three layers: exocarp, mesocarp and endocarp, the exocarp is thin and soft, the mesocarp is juicy, that is, the edible part, and the endocarp is uneven hardwoody, that is, the kernel as the saying goes, but in the fruit of many plants, the pericarp of the three-empty layer is usually indistinguishable; During fruit growth, the flower column and stigma usually wither, and the flower column and stigma do not fall off after the fruit of a few plants grows up. The peduncle develops into a fruit stalk, and the corolla and stamens usually wither and fall off;

The types of fruits are various, and can be divided into single fruits, poly-flower fruits and aggregate fruits according to the number of flowers or the number of pistils in a flower. According to the texture of the peel, it can be divided into fleshy fruit and dried fruit; According to the cracking or not of the peel, it can be divided into split fruit and closed fruit.

The fruit develops from the ovary.

The fruit that develops from the ovary is also known as the true fruit, and it is made up of seeds and peels. The formation of the pericarp is actually the continuous development of the ovary wall, which in turn develops into the fruit.

Formation of fruits.

1 The common characteristics of fruits are: both (peel) and (seeds). 2 The common feature of stems is that the stems of various plants are present (with knots, leaves or buds growing on the nodes).

The fruit of the plant develops from the ovary on the pistil of the flower, and the ovule in the ovary develops into the seed in the fruit.

Hello dear dear, the fruit in the formation has the following characteristics: the structure of the real fruit is relatively simple, and it is the outer skin and the inner part contains seeds. The pericarp is developed from the ovary wall, which can generally be divided into three layers: ectocarp, mesocarp and endocarp, and the exocarp often has stomata, keratin wax and epidermal hair.

The thickness of the three layers of peel varies depending on the type of fruit. Some are mixed with each other and are difficult to distinguish, such as the mesocarp and endocarp of tomatoes; In general, the mesocarp changes greatly in structure, and the mesocarp of some plants is composed of juicy, nutrient-rich parenchyma cells, distributed with vascular bundles, and becomes the fleshy edible part of the fruit, such as peaches, plums, apricots, etc.; The mesocarp of some plants often dries out and shrinks, forming a membranous or leathery, such as broad beans, peanuts, etc., and some become loose fibrous. The vascular tissue is well developed, such as the "tangerine network" of citrus; The endocarp of different plants also has its own characteristics, some plants have thick and juicy endocarp, such as grapes, while the endocarp of some plants is composed of bony stone cells, such as peaches, apricots, plums and walnuts.

I hope mine is helpful to you and I wish you a happy life!
