Mitochondria are oganelle found in plant and animal cells. These organelles are where aerobic respiration occurs. When viewed with a conventional light microscope, mitochondria are small, dark and often difficult to see. All of the material and organelles contained by the plasma membrane are collectively called protoplast.
Plant cells contain the following organelles :
Nucleus contains the nuclear DNA
Mitochondria site of production of the majority of cell energy
Chloroplast site of photosynthesis
Cell wall provides structural support
Cell membrane surrounds cytoplasm
Central vacuole maintains water balance and turgor
Rough endoplasmic reticulum site of assembly of protein products
Smooth endoplasmic reticulum site of synthesis of steroid and fat product
Golgi apparatus packaging and processing center for cell products
