A seed is composed of three main parts: an outer seed coat for protection, an embryo with the potential to develop into a new plant, and stored food reserves to provide energy for germination and early growth.
The seed plant portion of the phylogeny includes the gymnosperms and angiosperms. Gymnosperms are a group of seed-producing plants with exposed seeds, such as conifers and cycads, while angiosperms are flowering plants that produce seeds enclosed within a fruit.
The hard covering of seeds is primarily composed of the seed coat, which is made up of specialized tissues like the testa and the tegmen. These tissues provide protection to the seed during dormancy and help regulate water intake when germination occurs. Additionally, the endosperm or cotyledons found within the seed also contribute to the overall structure of the seed coat.

A vitreous seed is a small, opaque structure found in the vitreous humor of the eye. It is usually composed of proteins and cells that have clumped together due to various reasons such as aging, inflammation, or trauma. Vitreous seeds can sometimes float around in the vitreous humor and may cause visual disturbances or floaters.
A apple seed is much larger than a dandelion seed.
A seed IS a living thing. It is composed of a multicellular embryo plant with food (called the endosperm). It has a life expectancy and will eventually die, particularly if exposed to extreme temperatures.

An epistle., The seed-bearing organ of a flower. It consists of an ovary, containing the ovules or rudimentary seeds, and a stigma, which is commonly raised on an elongated portion called a style. When composed of one carpel a pistil is simple; when composed of several, it is compound. See Illust. of Flower, and Ovary.

Grape seed is the whole seed and grape seed extract is part of the seed which has been extracted from the whole.
The seed is the part of the nut known as walnut (Juglans spp) that is eaten.Specifically, nuts are considered fruits. Within the category of fruits, there are hard-shelled and soft-skinned members. Walnuts represent an example of hard-shelled fruits (or nuts) and are composed of a hard outer fruit and an edible inner seed.A popular example of soft fruits are apples (Malusspp).
A papaya seed is a seed from a papaya fruit.
The seed was sown.
Non-seed plants evolved from seed plants.
