Question

which organelles or structures are absent in plant cells?
○ mitochondria
○ microtubles
○ golgi apparatus
○ centrosomes
○ peroxisomes

Explanation:

To determine which structure is absent in plant cells, we analyze each option:

• Mitochondria: Present in plant cells (for cellular respiration).
• Microtubules: Present in plant cells (part of the cytoskeleton).
• Golgi apparatus: Present in plant cells (involved in processing proteins).
• Centrosomes: Plant cells lack centrosomes (they have different microtubule - organizing centers).
• Peroxisomes: Present in plant cells (involved in metabolic processes).

Answer:

D. centrosomes
