Answer:
Explanation:The main difference between seed and grain is that a seed is an embryonic plant whereas a grain is the seed or fruit of grasses. Furthermore, the three main parts of a seed are the embryo, endosperm, and the seed coat while grains contain an additional part called the pericarp or bran.
Seed and grain are two structures produced as a result of the sexual reproduction of higher plants. Also, nuts are another type of seeds produced by trees.

Difference Between Seed and Grain- Comparison Summary
What is a Seed
The seed is the fertilized ovules produced as a result of sexual reproduction of higher plants. Each seed contains an embryo, which can germinate to produce a new plant. Moreover, both angiosperms and gymnosperms produce seeds. In angiosperms, a fruit covers the seeds while gymnosperms do not produce fruit covering the seeds. Therefore, the seeds of gymnosperms are ‘naked’. However, seeds are an advanced method of dispersal of plants.

Figure 1: Seeds
Furthermore, the three main parts of a seed are the embryo, endosperm, and the seed coat. The embryo is the developed zygote, which further develops into a new plant. Secondly, the endosperm is the part of the seed, containing nutrients. It is formed as a result of triple fusion, which only occurs in angiosperms. Thirdly, the seed coat is the protective layer, which keeps the embryo safe.
What is a Grain
A grain is the seed of the grasses. Significantly, grains do not contain a fruit. This is due to the reliance of these seed on the wind for their dispersal. The four components of the grain are the embryo, endosperm, seed coat, and the bran. Here, their embryo and the endosperm are similar to those in a regular seed. The additional part of a grain is the pericarp or the bran. Wheat bran, rice bran, and corn bran are examples of bran, which is a mineral-rich, hard outer covering, protecting the embryo and the endosperm. Actually, bran is a part of the fruit, which fuses with the seed coat in grains.

However, grains are not designed by nature to be eaten. Also, most of them are toxic to animals at their raw state. Therefore, our ancestors ate a grain-free diet, which helped their good health. Also, grains contain a lower amount of nutrients. Therefore, most grainy foods are always fortified with vitamins and minerals. In addition, whole grains are more nutritious than the refined grains. On the other hand, most of the grains except rice contain gluten, which is a protein with stretches of repetitive amino acids. Unfortunately, gluten is difficult to digest by the body. Also, prolamins are another type of compounds present in grains with irritating effects to the immune system. Therefore, Crohn’s and Celiac disease, Irritable Bowel Syndrome and other digestive disorders are common illnesses which can occur as a result of the negative health benefits of grain
Similarities Between Seed and Grain
Seed and grain are two structures produced as a result of the sexual reproduction of plants.
Both structures are capable of developing into a new plant.
They contain an embryo, endosperm, and a seed coat.
