An embryonic plant wrapped in a protective outer shell is known as a seed. In seed plants, the spermatophytes, which include gymnosperm and angiosperm plants, the generation of a seed is a part of the reproduction process.

Any plant’s basic component is the seed. The seeds develop from the ovules after fertilisation. The embryo and the seed coat make up a seed. A radicle, an embryonal axis, and one or two cotyledons (wheat, maize) make up the embryo (gram and pea). When we plant a seed that we find inside a fruit, it grows into a new plant. As a result, the seed takes precedence.

Types of seeds:-

There are two basic sorts of seeds. The following are the two kinds:

  • Monocotyledonous Seed is a type of monocotyledonous plant that produces
  • Seed of a Dicotyledon

Structure of a monocotyledonous

A monocotyledonous seed has only one cotyledon, as the name implies. The seed coat has only one layering on the outside. The pieces of a seed are as follows:

  • Seed Coat:-The seed coat of cereals like maize is membranous and usually merged with the fruit wall, which is known as Hull.
  • Endosperm:-Food is stored in the endosperm, which is bulky. Monocotyledonous seeds are generally endospermic, however some, such as those found in orchids, are not.

Aleuron Layer:-The embryo is separated from the outer coating of the endosperm by a proteinous layer known as the aleurone layer.

Embryo:-The embryo is tiny and sits in a groove at one end of the endosperm.

Coleoptile and coleorhiza:Sheaths encase both the plumule and the radicle. Coleoptile and coleorhiza are the two terms used to describe them.

Structure of dicotyledonous

Dicotyledonous seeds have two cotyledons, unlike monocotyledonous seeds. The pieces are as follows:

  • Seed Coat:-This is a seed’s outermost covering. The outermost testa and the inner tegmen are the two layers of the seed coat.
  • Hilum:-The hilum is a scar on the seed coat that was used to adhere the growing seed to the fruit.
  • Micropyle:-There is a little pore above the hilum.
  • Endosperm:-The endosperm generated as a result of double fertilisation is a food-storing component in some seeds, such as castor. The endosperm is absent in mature seeds of plants such as bean, gramme, and pea. Non-endospermous is the term for them.
  • Radicle and Plumule:-They can be found on both ends of the embryonal axis.

Examples of Seeds

Wheat, rice, maize, sorghum, barley, peanut, soybean, lentil, common pea, common bean, coconut, walnut, pecan, and sunflower seeds are examples of such seeds. Many other seeds are eaten with their fruits, but the encasing fruit walls are usually the most sought-after source of nourishment.

Benefits of Seeds

Seeds contain all of the building blocks needed to grow into complex plants. They are particularly nutritious as a result of this.

Seeds are high in fibre. They also have beneficial monounsaturated and polyunsaturated fats, as well as numerous vitamins, minerals, and antioxidants.

Seeds can help lower blood sugar, cholesterol, and blood pressure when eaten as part of a healthy diet.

There are some benefits of Seeds you can eat.

  • Flaxseeds:-Flaxseeds, also called linseeds, are high in fibre and omega-3 fatty acids, especially alpha-linolenic acid (ALA).

The omega-3 lipids, on the other hand, are found in the seed’s fibrous outer shell, which is difficult for humans to digest.

As a result, if you want to boost your omega-3 levels, it’s preferable to eat ground flaxseeds (1 Trusted Source, 2Trusted Source).

  • Hemp Seeds:-Hemp seeds are a great vegetarian protein source. They actually contain more than 30% protein, as well as a variety of other necessary elements.

Hemp seeds are one of the few plants that are complete protein sources, containing all of the essential amino acids that your body cannot produce.

Hemp seeds also offer a higher protein quality than most other plant protein sources, according to studies (23 Trusted Source).
