Mitochondrion a singular word for mitochondria is a "powerhouse" organelle of the cell.
<span>Mitochondrion
is an important organelle in most living organisms because it is where
biochemical processes of living organisms such as respiration takes
place. The mitochondrion has a smooth outer membrane but a larger inner
membrane. The inner membrane is about 70% protein and is very convoluted
because that can even fit inside the outer membrane. Mitochondrion is
the carrier of the Kreb's cycle in the matrix and it is responsible for
the transfer of electron chain found in the cristae of the inner
membrane.</span>
The first scientific discovery is the epigenetic variation where it describes the deviation in the chemical tags that attach to DNA which affect how genes are read. Theses tags are called epigenetic markings that act as switches that control how genes can be read. Another essential discovery on human variation is the genetic variability, which measures the tendency of individual genotypes in a population to become different from one another. In addition, the variability of a trait is how much that characteristic tends to vary in response to environmental and hereditary influences.

They are semi-permeable because they can diffuse and pass through the plasma membrane easily.
