The correct answer for the question is option 2, mitochondrion. Mitochondria are often referred to as the "powerhouse" of the cell because they are responsible for producing the majority of the cell`s energy in the form of adenosine triphosphate (ATP) through a process called cellular respiration.

Let`s examine the other options to understand why they are not the correct answers:

1. Golgibody: Golgi bodies are involved in processing and packaging proteins for transport, but they do not generate energy.

3. Ribosome: Ribosomes are responsible for protein synthesis in the cell. They do not generate energy either.

4. Lysosome: Lysosomes contain enzymes that break down waste materials and cellular debris. They are not involved in energy production.

In conclusion, the mitochondrion is known as the powerhouse of the cell because it generates energy in the form of ATP through cellular respiration.
