What is a Funicle?

Where is Testa found?

How Testa is formed?

The seed coat develops from the maternal tissue, the integuments, originally surrounding the ovule. ... Bitegmic seeds form a testa from the outer integument and a tegmen from the inner integument while unitegmic seeds have only one integument. Usually parts of the testa or tegmen form a hard protective mechanical layer.

Where is Testa located?
