Q. In which of the following kinds of ovules, the embryo sac is horse-shoe shaped?
- Hemitropous ovule
- Orthotropous ovule
- Amphitropous ovule
- Circinotropous ovule
Solution :
Correct option : C
The embryo-sac is the female gametophyte borne within the ovule. The embryo-sac contains the egg cell, synergids, antipodals and the central cell. The embryo-sac acquires the horseshoe shape in amphitropous ovules because these ovules have a pronounced curvature. These are seen in the family Butomaceae. Hence, the correct answer is ‘Amphitropous ovule’
