Question

Which cells or cell group at the micropylar end of the mature embryo sac constitute the egg apparatus?

Options

• Three egg cells and two synergids

• One egg cell and two synergids

• One egg cell and three synergids

• One egg cell and two antipodal cells

Answer 1

The egg apparatus at the micropylar end consists of one egg cell and two synergids, making a total of three cells. The egg cell serves as the female gamete that fuses with the male gamete during fertilization, while the synergids have a filiform apparatus that helps guide the pollen tube towards the egg.
