Shared Organelles in Eukaryotic Cells

Steps:

• Identify structures unique to plant cells: cell wall (1) and chloroplasts (3).
• Identify structures common to both animal and plant cells: nucleus (2) and mitochondria (4).
• Eliminate options including plant-only structures.
• Select option listing only shared structures.

Why C is correct:

• Animal and plant cells both contain nucleus for genetic control and mitochondria for ATP production, per eukaryotic cell theory.

Why the others are wrong:

• A includes 1 (cell wall) and 3 (chloroplasts), which are absent in animal cells.
• B duplicates C but is listed separately; assuming intent, it may mislabel shared items.
• D includes 1 (cell wall), absent in animal cells.

Final answer: C
