  1. Mitochondria

    Mitochondria Mitochondria are responsible for energy production. They are also the responsible location for which respiration takes place. Mitochondria contain enzymes that help convert food material into adenosine triphosphate (ATP), which can be used directly by the cell as an energy sour

  2. Mitochondria 2

    Mitochondria Mitochondria are tiny organelles found in nearly all eukaryotic cells. They are rather large organelles ranging from 0.5µm to 10µm in length and 1µm in diameter. The mitochondria are the energy factories of the cell and are located in the cytoplasm. They are the sites of cellular

  3. Mitochondria and Chloroplast Essay

    I. Introduction Out of all the organelles there are two that have fascinated microbiologists for the past hundred years. The first is the mitochondria, nicknamed the "powerhouse of the cell." The second is the chloroplast in plant cells that have functions similar to those of the mitochondri

  4. Mitochondria

    Mitochondria are the cell's power producers. They convert energy into forms that are usable by the cell. Located in the cytoplasm, they are the sites of cellular respiration which ultimately generates fuel for the cell's activities. Mitochondria are also involved in other cell processes such as cell

  14. Mitochondria

    In cell biology, a mitochondrion (plural mitochondria) is a membrane-enclosed organelle found in most eukaryotic cells.[1] These organelles range from 0.5 to 1.0 micrometer (μm) in diameter. Mitochondria are sometimes described as "cellular power plants" because they generate most of the cell's sup

  15. The Endosymbiont Hypothesis and the Evolution of the Chloroplast and Mitochondria

    The Endosymbiont Hypothesis and the evolution of the Chloroplast and Mitochondria Dr Lynn Margulis is seen as the first person to have put forward the Endosymbiont Hypothesis which is based on a theory which explains the likely origin of the mitochondria and chloroplast (plants) in eukaryote orga

  16. Mitochondria

    Mitochondrion (plural, mitochondria), is found in nearly all eukaryotes. Plants, animals, fungi, and protists all have mitochondria. Mitochondria are large enough to be observed with a light microscope and were first discovered in the 1800s. For many years after their discovery, mitochondria were c
