They use mitochondria to release energy from sugars

Detailed explanation-1: -Like animal cells, plant cells also have mitochondria. The mitochondria play a critical role in integrating the sugar that is produced in the cell to generate energy. Mitochondria are necessary for plants to produce energy in ATP form, which is normally done during the day through photosynthesis.
Detailed explanation-2: -Furthermore, it is no surprise that mitochondria are present in both plants and animals, implying major commonalities in regulation, energy production, substrates employed, etc. This common presence of mitochondria, with similar functions and structure, underscores how close our life forms are.
Detailed explanation-3: -A fascinating parallel between plant and animal life is in the use of tiny energy factories within the cells to handle the energy transformation processes necessary for life. Both animal and plant cells contain mitochondria and plants have the additional energy factories called chloroplasts.
Detailed explanation-4: -As discussed above, mitochondria are the sites of respiration, and generate chemical energy in the form of ATP by metabolizing sugars, fats, and other chemical fuels with the assistance of molecular oxygen.
