Which of the following statements about endosperm is/are correct?
A) It surrounds the embryo and provides nutrition.
B) It is present in all seeds even after full development.
C) In non-albuminous seeds, it remains as a food reserve.
D) In albuminous seeds, it remains as a storage tissue.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) →A and D
A) It surrounds the embryo and provides nutrition.
D) In albuminous seeds, it remains as a storage tissue.
Explanation:
- The endosperm is a nutritive tissue that provides food to the developing embryo.
- In albuminous seeds (e.g., wheat, maize, and castor), the endosperm remains as a food reserve even after seed maturation.
- In non-albuminous seeds (e.g., pea, bean, and groundnut), the endosperm is completely consumed during embryo development.
Other options:
B) It is present in all seeds even after full development. – Incorrect
- In non-albuminous seeds, the endosperm is completely used up during embryo development, so it is not present in all seeds after full development.
C) In non-albuminous seeds, it remains as a food reserve. – Incorrect
- In non-albuminous seeds, the endosperm is not retained as a food reserve; instead, nutrients are stored in cotyledons.
Final Correct Answers:
A) It surrounds the embryo and provides nutrition.
D) In albuminous seeds, it remains as a storage tissue.
