The correct option is (A) to fuel their chemical reactions
A lot of biochemical reactions occur per minute inside living cells and these reactions have to be sustained because the survival of living cells depend on them. For these reactions to proceed, energy is needed. This energy is usually obtained from the food which a living organism consumed. The mitochondria, which is the power house of the cell, is the one which convert the energy to the ATP form, which is usable by the cells.

The presence of paired chromosomes makes a <u>diploid </u>cell, while a single member of a pair of chromosomes makes a<u>haploid </u>cell.
Diploid cells. Meiosis is the process of cell division by which involving gametes. Cell division is just the same for sperm and egg cells, but they have distinguishable descriptions and labels in the process. Spermatogenesis is for the males’ sperm cells and oogenesis is the process for females’ egg cells. The cell division of meiosis involves the two phases, respectively meiosis I and meiosis II. Meiosis I like mitosis is the cell division that produces diploid cells<span>. These diploid cells are cells that contain a complete pair of chromosomes which is 46. The result is two diploid cells after the first meiosis. To provide clear explanation, in contrast haploid cells only contain 23 chromosomes and are created after meiosis II which is 4 in number. </span>
