Read the following statements regarding double fertilization in angiosperms and choose the incorrect statement.

Options

  1. AThe central cell after triple fusion becomes the primary endosperm cell and develops into the endosperm.
  2. BThe synergids and antipodals degenerate after fertilization.
  3. CThe primary endosperm nucleus is formed by syngamy and develops into the embryo.
  4. DPrior to fertilization, the large central cell of the embryo sac contains two polar nuclei.

Correct answer

C. The primary endosperm nucleus is formed by syngamy and develops into the embryo.

Step-by-step solution

In angiosperms, double fertilization involves two distinct fusion events: syngamy and triple fusion. Syngamy is the fusion of one male gamete with the egg cell to form a diploid zygote, which subsequently develops into the embryo. Triple fusion is the fusion of the second male gamete with the two polar nuclei in the central cell to form a triploid primary endosperm nucleus (PEN). Following this, the central cell becomes the primary endosperm cell (PEC) and develops into the endosperm. Therefore, the statement claim
