Question

Which of the following statements is not true about somatic embryogenesis?

• A. The pattern of development of a somatic embryo is comparable to that of a zygotic embryo.
• B. Somatic embryos can develop from microspores.
• C. Somatic embryo is induced usually by an auxin such as 2, 4-D.
• D. A somatic embryo develops from a somatic cell.

Answer 1

Answer: (B)

Somatic embryos develop from somatic cells.Their development is comparable to that of a zygotic embryo. They are just like a normal embryo except that their development is induced from a diploid somatic cell. Somatic embryo culture is induced by a high concentration of an auxin. Microspores are haploid cells which do not give rise to somatic embryo.
