Mitochrondria of the eukaryotic cells.
<span>As many researchers hypothesize that the old single-celled organism or the origin of the complex-celled organisms came from the endosymbiosis of the mitochrondrion organism and the prokaryotic cell. It has been said that mitochondria was an independent organism which then to have been evovled itself after planting itself inside a prokaryotic cell which aided cellular respiration and production of ATP (Adenosine Triphosphate). This then aided the prokaryotic cell to be more sophisticated and caused another change from having without a true nucleus to a eukaryotic cell with a nucleus and embedded DNA. </span>
Answer:
Photosynthesis removes carbon from the atmosphere, and cellular respiration releases carbon back into the atmosphere.
Explanation:
Photosynthesis manufactures sugar from carbon dioxide from respiration and water using sunlight as the source of energy. Carbon dioxide diffuses through the stomata from the atmosphere and releases oxygen which is used in cellular respiration to break down food forming carbon dioxide, energy and water.
Vary in the number of neutrons but Sama in the number if protons are called isotopes
