Question

The number of chromosomes in an angiospermic plant is $14$. The number of chromosomes in synergid cells will be ______.

• A. $28$
• B. $21$
• C. $14$
• D. $7$

Answer 1

The correct option is D $7$

The pollen tube ultimately enters an ovule through the micropyle and penetrates one of the sterile cells on either side of the egg ( synergids). These synergids begin to degenerate immediately after pollination.

Synergids are haploid in nature. Thus, if the angiosperms plant cell has 2n = 14, synergids will have n = 7.
