Which of the following statements about endosperm development is true?
Endosperm development precedes embryo development.
Endosperm is triploid in all angiosperms.
The primary endosperm cell forms a diploid endosperm tissue.
Endosperm provides nutrition to the developing embryo.
Answers (1)
Endosperm development occurs prior to embryo development. Following fertilisation, the primary endosperm cell divides repeatedly to generate endosperm tissue. Endosperm tissue is triploid, which means it has three sets of chromosomes. Endosperm tissue cells are loaded with reserve food components like as carbohydrates and proteins, which provide sustenance to the developing embryo. Until the embryo can create its own food delivery system, the endosperm provides vital nutrients for its growth and development.
Hence, the correct answer is option 4.
