They are the membrane-bound cell organelles, which produce the majority of the chemical energy required to power the biochemical reactions within the cell.
The chemical energy generated by the mitochondria is captivated in a small molecule known as ATP or adenine triphosphate.
The egg is the female haploid gamete and sperms are the male gametes, which take part in the process of sexual reproduction.
During sexual reproduction, the sperm fuses with the egg to give rise to a diploid zygote, which further goes through many transitions to produce the embryo.
The process, by which the production of offspring takes place is termed reproduction. It is of two kinds, that is, sexual and asexual modes of reproduction.
It is found that within the egg more amount of mitochondria is present in comparison to sperms.
Due to this, the transferring of the mitochondrial genome takes place from the mother to the offspring.
Sperm also comprise mitochondria in the middle piece, which provide energy for its movement.
