This organelle is the “powerhouse” of the cell; it breaks down food to release energy (Analogy:power plants or food processing plants of a city)
A
vacuole
B
mitochondria
C
nucleus
D
ribosome
Explanation: 

Detailed explanation-1: -Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the powerhouses of the cell.

Detailed explanation-2: -The mitochondrion is referred to as the ‘power house’ of the cell, because it is responsible for the synthesis of the majority of ATP under aerobic conditions. The inner membrane of the mitochondrion contains the components of the electron transport chain.

Detailed explanation-3: -Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell.

Detailed explanation-4: -Mitochondria is called the powerhouse of the cell as it releases energy to perform various functions of the cell.

Detailed explanation-5: -Mitochondria are known as the powerhouse of cells. It is because the mitochondrion is the site of cellular respiration where energy in the form of ATP (Adenosine triphosphate) is generated as a result of oxidation of food constituents. This energy is required for various chemical activities needed for life.
