Embryo & endosperm
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 seed covering, also known as a seed coat, is the outer protective layer that encases a seed. It helps to protect the seed from physical damage, pathogens, and drying out. The seed covering can vary in thickness and composition depending on the plant species.
The protective covering around the seed of an angiosperm is called the seed coat. It helps to protect the seed from damage and drying out, ensuring its viability during dormancy.
A seed protector is a covering or barrier that helps shield seeds from harsh environmental conditions such as extreme temperatures, pests, or diseases. It can be a physical covering, like a seed coat, or a chemical protection mechanism within the seed itself.
The seed coat or testa is a protective covering that forms around the fertilized ovule.The coating is normally hard and water resistant and provides protection from dessication (drying out). Additionally the seed coat also allows the seed to be eaten by certain animals and birds which then pass the seed undigested through their digestive tracts and facilitate dispersal of the seeds. The seed coat is formed in the ovary shortly after fertilization from the integument.Once the correct conditions have been met for germination the seed coat will start to absorb water, soften and eventually split as the embryo inside starts to absorb water, swell and germinate.

The hard covering of a seed is called the seed coat. It serves to protect the seed from damage, dehydration, and pathogens.
'Aril' is the scientific name for seed covering
The outer covering of the grain is called Husk.

Some seeds have an outer covering which makes it hard for insects and animals to get into. Sunflower seeds have a hard outer shell to protect itself from predators.
If you mean the seed covering its called the Testa
The protective covering around the seed of an angiosperm is called the seed coat. It helps to protect the seed from damage and drying out, ensuring its viability during dormancy.
For the sunflower (Helianthus annuus), the seed is a multilayered future plant that is enjoyed as a food source by many. What you see, when you have a sunflower seed, is the hard shell. It can be all black or striped. Break that open and you have the actual seed. The outer most covering on the seed, usually you don't notice it, is call the integumentary or seed coat.
It protects it's seed with the outer shell covering.
