Solution:

Mitochondrion is a structure within the cytoplasm of eukaryotic cells that carries out aerobic respiration. It is the site of the Krebs' cycle and electron transport chain, and therefore the cell's energy production. Mitochondria vary greatly in shape, size, and number but are typically oval or sausage-shaped and bounded by two membranes, the inner one being folded into finger-like projections (cristae); they contain their own DNA and 70S ribosomes.
