Is melon seed shell a seed coat? What is the main ingredient of melon seed skin

In view of the fact that too many people think that melon seed shells are seed coats, I revised the answer for the third time, hoping that everyone will distinguish it in the future (don't talk nonsense if you don't know, thank you!). ）

The melon seed shell is the peel!

The shell of sunflower seeds is not the same as the shell of watermelon seeds!

Sunflower seeds are the fruit of the sunflower plant, and the melon seed shell is developed from the bead wall of the embryo of the plant, so the melon seed shell is the peel. The seeds of sunflowers are the edible part of the melon seeds, and there is a film on the outside, which is the seed coat.

Watermelon seeds are different, watermelon is the fruit, watermelon skin is the peel, watermelon seeds are seeds, and the skin of watermelon seeds is developed by the ovary wall, so the shell of watermelon seeds is the seed coat.

Both: the shell of the sunflower seed is the peel, and the shell of the second watermelon seed is the seed coat.

I believe that this kind of question should be a hot topic in middle and high school biology discussions, and ask middle and high school students, they should explain it more clearly.

One more thing to add:

The seed is a part of the structure under the peel. Some fruits contain only one seed, while others contain many seeds.

Sunflower seeds are achenes, and removing what we call melon seed shells from the outside is its seeds;

Corn kernel is the fruit of the grasses, is the unique fruit of the grasses, millet and wheat belong to the fruit of the fruit, because the peel is not cracked, and the seed coat is highly healed, so the production of the fruit is directly called the seed of the plant;

Watermelon is a gourd fruit, and watermelon seeds are its seeds.

Reference place.

The melon seed shell should be the seed coat.

I'm pretty sure sure and definitely.

The melon seed shell should be the seed coat.

The main components of melon seed skin are cellulose, lignin, hemilignin and a small amount of sugars and minerals.

Introduction to melon seed skin: melon seed skin is the seed coat that is coated outside the melon seed fruit. The skin of melon seeds will show different colors depending on the type of melon seeds, and the common colors are black and white.

Uses of melon seed peel:

1. Combustion. The peel of plum melon seeds contains a large amount of carbon and hydrogen, and the gas produced is pollution-free;

2. Fertilizer. The skin of the melon is rich in carbohydrates such as cellulose and can be used as an organic fertilizer.

It is mainly composed of organic compounds composed of carbon, hydrogen, and oxygen.

The main component of wood is cellulose, in addition to a small amount of starch and protein.

1. The skin of melon seeds is what is left after people finish gramming melon seeds, it is just a seed coat and has no application value.

2. Its main components are cellulose, lignin, hemilignin and a small amount of sugars and minerals.

It is harmless, but the melon seed shell is not easy to digest, and it is not suitable to eat.

Some melon seed shells, such as watermelon seeds and sunflower seeds, are relatively hard, especially after biting, they may form a pinprick shape, which may puncture the esophagus. Basically, they are eaten without shells.

The shell of pumpkin seeds is easier to chew, and some people chew and eat it with the shell. The actual pumpkin seed shell is also not easy to digest, and it is better to remove the shell.

No matter what kind of melon seeds, there are unhygienic factors in the process of frying and transportation, and they should be eaten without shelling.

In addition, although melon seeds are delicious and nutritious, they are not suitable for children. It often happens that young children eat melon seeds and stab their throats, esophagus or melon seeds enter the trachea, especially the latter case, which is more dangerous and parents should pay attention to.

I can't digest it if I eat it, and I can't eat it.

The main component of wood is cellulose, in addition to a small amount of starch and protein.
