Besides activating egg, another role of sperm is to carry ............[Odisha 2009]
(a) RNA (b) Ribosomes (c) Mitochondria (d) DNA
Because the main role of sperm is to carry DNA.
After the fusion of plasma membrane of sperm and egg cell at the time of fertilisation, only nucleus i.e., only DNA enter the egg cell, and mitochondria is degenerated. Thus, mitochondria is not carried inside the egg cell.
Hope this helps :)
