what is the function of mitochondrion in a plant cell
Mitochondrion Mitochondria are commonly between 0.75 and 3 μm in diameter[5] but vary considerably in size and structure. Unless specifically stained, they are not visible. In addition to supplying cellular energy, mitochondria are involved in other tasks, such as signaling, cellular differentiation, and cell death, as well as maintaining control of the cell cycle and cell growth.[6] Mitochondrial biogenesis is in turn temporally coordinated with these cellular processes.[7][8] Mitochondria have been implicated in several human diseases, including mitochondrial disorders,[9] cardiac dysfunction,[10] heart failure[11] and autism.[12]
Electron transport chain Electron transport chains are used for extracting energy via redox reactions from sunlight in photosynthesis or, such as in the case of the oxidation of sugars, cellular respiration. In eukaryotes, an important electron transport chain is found in the inner mitochondrial membrane where it serves as the site of oxidative phosphorylation through the use of ATP synthase. It is also found in the thylakoid membrane of the chloroplast in photosynthetic eukaryotes. In bacteria, the electron transport chain is located in their cell membrane.
