In an introductory comparison of eukaryotic organelles, which structure is typically found in animal cells but not in plant cells?

• A. Centrioles (in the centrosome), which help organize microtubules during cell division
• B. A cellulose cell wall, which provides rigid support
• C. A large central vacuole, which helps maintain turgor pressure
• D. Chloroplasts, which carry out photosynthesis

Answer: (A)

Verified step by step guidance

1. Step 1: Understand the key differences between plant and animal cells, focusing on their organelles and structures.
2. Step 2: Identify organelles that are unique to plant cells, such as the cellulose cell wall, large central vacuole, and chloroplasts, which are absent in animal cells.
3. Step 3: Recognize that centrioles, which are part of the centrosome and help organize microtubules during cell division, are typically found in animal cells but not in plant cells.
4. Step 4: Compare the functions of each organelle listed to confirm which one is exclusive to animal cells.
5. Step 5: Conclude that centrioles are the structure typically found in animal cells but not in plant cells, distinguishing them from the other options.
