Options
- AThe egg apparatus is situated at the chalazal end and consists of two synergids and one egg cell.
- BSix of the eight nuclei are surrounded by cell walls and organised into distinct cells.
- CThe large central cell contains three polar nuclei prior to the event of fertilization.
- DThe filiform apparatus is a characteristic cellular thickening found at the micropylar tip of the antipodal ce
Correct answer
B. Six of the eight nuclei are surrounded by cell walls and organised into distinct cells.
Step-by-step solution
In a typical mature embryo sac of an angiosperm, the egg apparatus is situated at the micropylar end and consists of two synergids and one egg cell. Six of the eight nuclei are surrounded by cell walls and organised into distinct cells. These include three cells at the micropylar end forming the egg apparatus and three cells at the chalazal end forming the antipodals. The large central cell contains two polar nuclei, not three. The filiform apparatus is a characteristic cellular thickening found at the micropylar t
