(a) full mature embryo
(b) cotyledons with endosperms
(c) cotyledons filled with starch
(d) half mature embryo
Answers
Answer:
The answer is: (A) full mature embryo.
Explanation:
Testa is the outer layer that makes the seed coat that protects the inner part of the seed. When the seed coat of a dicotyledonous seed coat is removed, the embryo appears. If the testa is removed from water-soaked gram seed, then the remaining structure will be a fully mature embryo, which is distinguishable into cotyledon and the radicle.
If testa is removed from water soaked gram seed, the remaining structure is full mature embryo.
Answer: Option (a)
Explanation:
- An "embryo" is defined as an advanced stage of "multicellular organism".
- Testa is the outer layer of seed coat, which is a protective cover of seeds.
- An embryo mature from an "ovule after fertilization".
