egg contains almost all organelles, materials, and nutrition for zygote growth. That is why it is bigger then a sperm cell

Egg cells are considerably larger than sperm cells because they carry the cytoplasm and organelles necessary for cell division and growth to begin, while sperm cells are basically a cell nucleus and a tail.
