(b) Testa and tegmen are closely attached that they can’t be separated unless soaked in water

(c) Seed coat provides protection to the embryo

(d) Testa is the thin inner layer and tegmen is the thick outer layer of a seed coat

The question was posed to me during an interview.

My question is from Flowering Plants Morphology in division Morphology of Flowering Plants of Biology – Class 11

Answer 1

Right option is (d) Testa is the thin inner layer and tegmen is the thick outer layer of a seed coat

The best I can explain: Testa and tegmen are the two layers of a seed coat. These are so closely attached that they can’t be separated unless soaked in water. Testa is the thick outer layer and tegmen is the thin inner layer of a seed coat .Seed coat provides protection to the embryo.
