The fruits we eat are not necessarily "pulp"?In fact, these "parts" →

In the hot summer, the most anticipated is the variety of fruits, delicious and juicy, which is a must -have for summer heat. However, when you are happy, have you ever wondered, is it the fruit of the fruit?

Delicious fruit

People are accustomed to that the fleshy part of the flesh when eating fruits is their flesh. In fact, there is no concept of "flesh" in botanicals. Because when the fruit or flowers, the seeds are not seeds, but are called embryo. These little guys who have high hopes are born in the pistil's child's room and protected by the child wall. With the growth of the embryo beads, the child's house that protects them has also developed into the most dazzling part of the plant -fruit.

This fruit developed from the sub -room is called real fruit. The fruits of most plants belong to the real fruit. The structure of the real fruit is simple, and it is the peel (the wall of the child's room develops), and the inside contains seeds (the beads develop). The peel can be divided into outer fruit, medium -sized peel, and internal skin. In different fruits, the three layers of peels are very different. In addition to the sub -room, there are other parts, such as flower care, calyx, and inflorescence shafts.

peach

Taking peach as an example, the thin layer of the peeling layer is its skin. The peach core and the peach kernel inside are inner skin and seeds. Therefore, the fat and juicy peach meat that everyone eats is actually a meaty peel. This type of fruits also include apricots, Li, Mei, cherry, etc. belonging to the family of Rosaceae.

tangerinr

Not all fruits are as "serious" as peaches. For example, the best part of orange fruits is actually in the inner peel. What is it?

It is because the multi -cell epidermis of the internal skin is specially transformed into a juicy "meat strip". In short, the part we eat is "orange hair". Part of the peel, and the "orange" that the "orange" that the "obsessive -compulsive disorder" babies dislikes the inner layer of the Chinese skin.

strawberry

The point of the strawberry epidermis can plant strawberries, but this small black point is not the seed of strawberries. The small dots distributed on the surface of the strawberry are the real fruits. This one of them gathered together. In botanical, we call it "polymerization fruit". The red part we eat is its expansion of meat.

watermelon

The flower of watermelon also participated in the development of fruit, but it was only in the "watermelon peel" part. If the watermelon surface is cut in half, you will find the three internal divisions similar to the heart shape. The parts outside the boundary line are the middle and inner layers of peels after the flesh expansion. Within the boundary line, the soul of the watermelon is — that is, the melon we eat, which is actually its fetal seat (where the raw beads).

litchi

Dipping the lychee uneven housing with a layer of white film inside, which is its internal skin. And we usually eat fat, crystal clear parts of lychee.

The fake seeds of lychee develop from the bead handle (the part of the beads and the fetal seat) and its fetal seat. Fake seed skin is a special type of species of peeling belonging. It is a structure developed by seed plants to adapt to the environment. It has important biological research value. Like litchi, the edible parts of many tropical fruits such as longan and durian are fake skin.

I know so much before I know

It turns out that the fruits we eat are not necessarily the flesh

Therefore, everyone is ready to eat fruit

Epropherbon, fetal seat or fake seed skin?
