Name the component cells of the ‘egg apparatus’ in an embryo sac.

Answers (1)

The egg apparatus consists of two synergids and one egg cell.

  1. One egg cell: This will fuse with a sperm cell during fertilization to form the zygote, which eventually develops into the embryo. This embryo continues to develop and mature, laying the foundation for the formation of a complete individual.

  2. Two synergids: These are located on either side of the egg cell and play a significant role in guiding the pollen tube to the egg cell for fertilization. They secrete chemical signals that help attract and guide the pollen tube toward the egg cell, ensuring the delivery of sperm cells for successful fertilization.
