Which structure is not found in plant cells?

• A. Chloroplast
• B. Cell wall
• C. Centrioles
• D. Central vacuole

Answer: (C)

Verified step by step guidance

1. Step 1: Understand the key organelles and structures typically found in plant cells. Plant cells usually contain chloroplasts, a cell wall, and a large central vacuole, which are essential for photosynthesis, structural support, and storage, respectively.
2. Step 2: Recall the function and presence of centrioles. Centrioles are cylindrical structures involved in cell division and are typically found in animal cells but are generally absent in most plant cells.
3. Step 3: Compare each option with the known components of plant cells: chloroplasts (present), cell wall (present), central vacuole (present), and centrioles (absent).
4. Step 4: Conclude that the structure not found in plant cells among the options given is centrioles, as plant cells use other mechanisms for cell division that do not involve centrioles.
5. Step 5: Summarize that identifying organelles unique to plant or animal cells helps in understanding cell structure and function differences between these two cell types.
