Question

which organelles are not found in plant cells?
vacuoles
mitochondria
chloroplasts
centrioles

Explanation:

To determine which organelle is not found in plant cells, we analyze each option:

• Vacuoles: Plant cells have large central vacuoles, so this is incorrect.
• Mitochondria: Both plant and animal cells have mitochondria for energy production, so this is incorrect.
• Chloroplasts: Plant cells (especially in photosynthetic tissues) have chloroplasts for photosynthesis, so this is incorrect.
• Centrioles: Most plant cells lack centrioles (they are more common in animal cells and some lower plants).

Answer:

D. centrioles
