Which part of the cell is membrane bound, helps with protection storage, waste disposal, and growth?

• A. Ribosomes
• B. Golgi apparatus
• C. Endoplasmic reticulum
• D. Vacuoles

Answer: (D)

Vacuoles are membrane-bound sacs that handle storage, waste isolation, and, in plant cells, growth. They store water, nutrients, pigments, and wastes, and the large central vacuole in plants uses water uptake to create turgor pressure, which helps the cell expand during growth. This combination of storing materials, keeping unwanted substances separated, and supporting cell enlargement fits the described role. Ribosomes are not membrane-bound and focus on protein synthesis. The Golgi apparatus packages and ships materials. The endoplasmic reticulum is a factory network for making and transporting proteins and lipids. Vacuoles best match the functions of protection, storage, waste disposal, and growth.
