Verified step by step guidance

Step 1: Understand the role of mitochondria in eukaryotic cells. Mitochondria are known as the 'powerhouses' of the cell because they are the primary site of ATP production through cellular respiration.

Step 2: Recall that mitochondria are found in eukaryotic cells, not prokaryotic cells. Prokaryotic cells lack membrane-bound organelles, including mitochondria.

Step 3: Note that mitochondria contain their own DNA and ribosomes, which allow them to produce some of their own proteins independently of the cell's nucleus.

Step 4: Clarify that protein synthesis in the cytoplasm is carried out by ribosomes, not mitochondria. Mitochondria are not responsible for this process.

Step 5: Based on the above points, identify the correct statement: 'Mitochondria are the primary site of ATP production in eukaryotic cells' and 'Mitochondria contain their own DNA and ribosomes.' These are true statements about mitochondria.
