Question

The suspensor during the development of an angiosperm embryo is formed from

• A. Basal cell
• B. Apical cell
• C. Embryonal cell
• D. Generative cell

Answer 1

Answer: (A)

Basal cell

The diploid zygote in angiosperms divides mitotically to give rise to embryo. At the initial stage embryo divides transversely to form two celled pro-embryo consisting of upper terminal cell and lower basal cell. The basal cell divides repeatedly to form multicellular structure called suspensor while terminal cell divides repeatedly to form embryo proper.

Thus, the correct answer is option A.
