Verified step by step guidance

Step 1: Understand the function of ATP production in eukaryotic cells. ATP (adenosine triphosphate) is the primary energy currency of the cell, and its production is essential for cellular processes.

Step 2: Recall the role of organelles in ATP production. The mitochondrion is the organelle responsible for producing ATP through cellular respiration, specifically in the processes of glycolysis, the citric acid cycle, and oxidative phosphorylation.

Step 3: Compare the functions of the listed organelles: The nucleolus is involved in ribosome synthesis, the Golgi apparatus is responsible for protein modification and transport, and lysosomes are involved in breaking down cellular waste. None of these organelles are directly involved in ATP production.

Step 4: Relate the mitochondrion's function to its appearance in photomicrographs. Mitochondria are often visible in tissue samples, such as tracheal tissue, due to their abundance and role in energy production for active cells.

Step 5: Conclude that the mitochondrion is the correct answer based on its primary role in ATP production and its relevance to the energy needs of tracheal tissue.
