Mitochondria are found in both plant cells and animal cells.
Mitochondria are known as the powerhouses of the cell because they generate most of the cell’s supply of adenosine triphosphate (ATP), used as a source of chemical energy. Both plant and animal cells require energy to carry out their functions, which is why mitochondria are present in both types of cells.
In plant cells, mitochondria work alongside chloroplasts, which are responsible for photosynthesis. While chloroplasts convert light energy into chemical energy, mitochondria convert that chemical energy into ATP, which is used by the cell.
In animal cells, mitochondria are crucial for processes like respiration and energy production. Without mitochondria, animal cells would not be able to produce the energy needed to sustain life.
Therefore, the correct answer is c) both plant cells and animal cells.
