The product is a structure in which the embryo is protected from temperature extremes by its state of desiccation and is often guarded from further drying and from mechanical or biological degradation by the seed coats. The seed coat often contributes to the maintenance Read More; seed dormanc

Examples of testa in the following topics: Development of the Seed. In dicots, the seed coat is further divided into an outer coat, known as the testa, and inner coat, known as the tegmen.; The seed coat forms from the two integuments or outer layers of cells of the ovule, which derive from tissue from the mother plant: the inner integument forms the tegmen and the outer forms the testa In biology, a test is the hard shell of some spherical marine animals, notably sea urchins and microorganisms such as testate foraminiferans, radiolarians, and testate amoebae. The term is also applied to the covering of scale insects. The related Latin term testa is used for the hard seed coat of plant seeds

Seed is fertilized and ripened the ovule. It contains an active embryo. It reserves food for its development. Each seed is covered by two protective seed coats. The outer seed coat is called as testa and inner seed coat is called as tegmen. Micropyle is present on the covering of the seed <iframe src=https://www.googletagmanager.com/ns.html?id=GTM-N45B4XX height=0 width=0 style=display:none;visibility:hidden></iframe> <iframe src=//www.

In testas, all stages of the nematode are found in young seeds and numbers in excess of 35,000 nematodes per testa have been commonly recorded. Nematodes are found mainly in the sub-epidermal parenchymatous layer of testas where walls are broken and cells enlarged, and around the tracheids The seed, along with the ovule, is protected by a seed coat that is formed from the integuments of the ovule sac. In dicots, the seed coat is further divided into an outer coat known as the testa and inner coat known as the tegmen.
