The other name for seed integuments is "testa." The testa is the protective outer layer of a seed, which develops from the integuments of the ovule after fertilization. It serves to safeguard the seed's internal structures and can vary in thickness and texture among different plant species.
Integuments, after fertilization turn to the seed coat, which protects the seed
After fertilization, the integuments of the ovule develop into the seed coat, providing protection to the developing embryo inside. The seed coat also helps with seed dispersal and dormancy.
Integuments protect the body from physical harm, pathogens, and UV radiation. They also help regulate body temperature, provide sensory information through touch receptors, and aid in the production of Vitamin D when exposed to sunlight.
Integuments are modified to form the seed coat but hardening is not essential.
The sperm cell consists of 3 parts: the head (with the acrosomal vesicle, nucleus and centriole), midpiece (containing mitochondria) and tail (for movement). Enclosing all of this is a cell membrane

The testa is the outer seed coat that develops from the integuments of the ovule, while the tegmen is the inner seed coat that also originates from the integuments but lies closer to the seed.
The ovule of an angiosperm, which will eventually become a seed, is surrounded by integuments. They are layers of protective sporophytic tissue that eventually develop into the seed coat.

An angiosperm seed coat is formed from toughened parts of the ovule wall. This wall provides protection for the developing embryo and seed contents. It also helps prevent desiccation and mechanical damage during seed dispersal.
Inside the ovule, you will find the female gametophyte, which includes the egg cell. This is surrounded by protective layers such as the integuments, which eventually develop into the seed coat after fertilization. The ovule also contains the structures necessary for fertilization and seed development.
The seed coat provides protection for the seed, helping to prevent damage from physical and environmental factors like pests, disease, and extreme temperatures. It also helps regulate water uptake and germination, ensuring the seed develops properly.
Cotyledon is also known as seed leaf. It is the first leaf or pair of leaves produced by the embryo of a seed plant.
In fact the development of a seed starts from an ovule, the ovule primordium develops on the placenta of the ovary. It gets enclosed by the outer and inner integuments, which form the seed coat on maturity. Thus seed coat develops first and after fertilization the embryo comes in to being.
