Over the years, the safety of many food additives, from food dyes to trans fats, has come into question. A scare over a food additive may linger in our minds long after researchers find that there's actually no cause for alarm.
In cell biology, a mitochondrion (plural mitochondria) is an organelle found in most eukaryotic cells. Mitochondria are sometimes described as cellular power plants, because their primary function is to convert organic materials into energy.

The mitochondrion (plural mitochondria) is a double membrane-bound organelle found in most eukaryotic cells. The word mitochondrion comes from the Greek Î¼Î¯ÏÎ¿Ï, mitos, i.e. thread, and ÏÎ¿Î½Î´ÏÎ¯Î¿Î½, chondrion, i.e. granule or grain-like.Mitochondria range from 0.5 to 1.0 Î¼m in diameter.or instance, red blood cells have no mitochondria, whereas liver cells can have more than 2000. The organelle is composed of compartments that carry out specialized functions. These compartments or regions include the outer membrane, the intermembrane space, the inner membrane, and the cristae and matrix.
