1.Sexual Reproduction in Flowering Plants
medium
Egg apparatus of angiosperms consist of
A
One synergid and two egg cells
B
Two synergids and one egg cell
C
One central cell, two synergids and three antipodal cells
D
One egg cell, two polar nuclei and three antipodal cells
Solution
In embryo sac of angiosperm, egg apparatus occurs towards micropylar pole and generally organises by two synergids and one egg cell. Egg cell has a large vacuole at its upper and a prominent nucleus near its lower end. Synergids show a filiform apparatus attached to their upper wall. It is known to attract and guide the pollen tube. Each of the synergids has a vacuole at its lower end and the nucleus at its upper end.
