Solution

The correct option is D

Secondary nucleus


The correct option is D.

Explanation for correct option:

  1. A diploid nucleus that is formed by the fusion of two polar nuclei is called a secondary nucleus.
  2. It is also called as primary endosperm nucleus as it further develops into the endosperm.

Explanation for incorrect options:

Option A:

  1. Synergids are two small and specialized cells found within embryosac that lies adjacent to egg cells in the female gametophyte of an angiosperm.
  2. Synergids help in the nourishment of the ovum.
  3. It also plays an important role in guiding the pollen tube.

Option B:

  1. A zygote is a fertilized egg formed by the fusion of an ovum with a sperm.
  2. It develops into an embryo.

Option C:

  1. Three haploid antipodal cells are present at the chalazal end of the embryosac.
  2. The antipodal cells have a role in the provision of nutrition to the embryo.

Final answer: Endosperm of angiosperms forms after fertilization from the diploid nucleus.
