A) single celled
B) six celled
C) seven celled
D) eight celled
Correct Answer: C
Solution :
The female gametophyte of angiosperm is also known as embryo sac and is mostly a 7 celled structure. There is a large central cell with 2 polar nuclei, which later fuse to form secondary nucleus. The micropylar end of the embryo sac is occupied by egg apparatus, made up of one egg cell and two synergids and at its chalazal end 3 antipodal cells are present. Thus, it is a 7 celled and 8 nucleated structure.
