ATesta outside and tegmen inside
BTegmen outside and testa inside
CTesta outside and aleurone inside
DTegmen outside and aleurone inside
Answer & Solution
Correct answer: A. Testa outside and tegmen inside
1. The seed is protected by a seed coat formed from the integuments of the ovule sac.
2. In dicots that coat is further divided into an outer coat, the testa, and an inner coat, the tegmen.
3. So testa is outside and tegmen inside.
4. In monocot seeds the testa and tegmen are fused rather than distinct.
5. The aleurone is not part of the coat at all but a cell layer just inside it.
