Question

what structure in plant cells stores salts, sugars, and pigments, contains enzymes that recycle and degrade molecules, and expands to exert turgor pressure? multiple choice
centrioles
chloroplast
peroxisome
central vacuole

Explanation:

• Centrioles: Involved in cell division (animal cells mainly), not for storage/degradation or turgor.
• Chloroplast: Site of photosynthesis, stores chlorophyll (pigment) but not salts/sugars generally, no degradation enzymes.
• Peroxisomes: Involved in lipid metabolism and detoxification, not major storage or turgor contributor.
• Central vacuole (in plant cells): Stores salts, sugars, pigments; has enzymes for molecule degradation/recycling; expands to create turgor pressure.

Answer:

Central vacuole
