Explanation:

Question 6 (Lysosomes function)

Lysosomes are organelles with digestive enzymes. Option a is for ribosomes/endoplasmic reticulum (build macromolecules), option b is for Golgi apparatus (package), option d is for storage organelles like vacuoles. Lysosomes break down macromolecules, so option c is correct.

• Cell walls: Only in plant, fungi, bacteria cells (not animal).
• Centrioles: Mostly in animal cells, some lower plants.
• Chloroplasts: Only in plant cells (for photosynthesis).
• Mitochondria: Present in both, as they produce energy (ATP) for cells. So option d is correct.

Answer:

c. Lysosomes break down lipids, carbohydrates, and proteins.
