Verified step by step guidance

Step 1: Begin by understanding the function of ATP (adenosine triphosphate). ATP is the primary energy currency of the cell, used to power various cellular processes.

Step 2: Review the role of organelles in energy production. The mitochondrion is the organelle responsible for producing ATP through cellular respiration, specifically in processes like the Krebs cycle and oxidative phosphorylation.

Step 3: Compare the functions of the other organelles listed in the question: The nucleus is responsible for storing genetic material and regulating gene expression, the Golgi apparatus modifies, sorts, and packages proteins, and lysosomes are involved in breaking down waste materials and cellular debris.

Step 4: Relate the function of the mitochondrion to the high energy demands of intestinal villi. Intestinal villi are responsible for nutrient absorption, which requires significant energy, making mitochondria essential for ATP production in these cells.

Step 5: Conclude that the mitochondrion is the correct answer based on its role in energy production, which aligns with the energy needs of intestinal villi cells.
