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: -Just as photosynthesis occurs in organelles called chloroplasts, cellular respiration takes place in organelles called mitochondria. Remember that mitochondria are in both plant cells and animal cells, so both kinds of cells release energy through cellular respiration.
Detailed explanation-4: -Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
Detailed explanation-5: -Mitochondria: the energy converters Mitochondria, using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell. The process is called oxidative phosphorylation and it happens inside mitochondria.
