What consists of egg apparatus?

The egg apparatus is a structure found inside the embryo sac of flowering plants (angiosperms). It plays a crucial role in fertilization. The egg apparatus consists of the following three cells:

1. One Egg Cell:
   • It is the female gamete.
   • Located centrally within the egg apparatus.
   • It fuses with the male gamete (sperm cell) during fertilization to form the zygote.
2. Two Synergids:
   • These are helper cells that flank the egg cell—one on each side.
   • They help in guiding the pollen tube toward the egg cell using chemical signals.
   • Synergids contain a structure called the filiform apparatus, which facilitates nutrient and signal exchange.

Summary:

The egg apparatus = 1 egg cell + 2 synergids, all located at the micropylar end of the embryo sac.
