Which of the following organelles acts as the cell's powerplant?
nuclei
lysosomes
vacuoles
mitochondria

Option D. Mitochondria

Explanation:

Mitochondria is an organelles that act as the power plants of the cell.

Mitochondria is surrounded by two membranes, and have their own genome. The outer of membrane of mitochondria surrounds inner membrane completely with small intermembrane space in between.

The inner membrane contains proteins which participates in electron transport and ATP synthesis. the inner membrane surrounds the mitochondrial matrix and during the citric acid cycle, it produces electrons which further travel from one protein complex to other protein in the inner membrane. As the result of this electron transport chain, oxygen accepts the final electron and forms water and at the same time ATP is produced.

Hence, the correct option is mitochondria.
