Question

what is responsible for producing energy in both plant and animal cells?
a) cytoplasm
b) nucleus
c) mitochondria
d) bacteria

Explanation:

• Cytoplasm: It is the jelly - like substance within the cell that holds organelles. It is not the main site of energy production.
• Nucleus: Controls cell activities and stores genetic information. It is not involved in energy production.
• Mitochondria: Known as the "powerhouse of the cell", it produces ATP (adenosine triphosphate) through cellular respiration, which is the energy currency of the cell. This process occurs in both plant and animal cells.
• Bacteria: Bacteria are single - celled organisms, not cell organelles responsible for energy production in plant and animal cells.

Answer:

C. Mitochondria
