In animal cells, which membrane-bound cell organelles are generally smaller and help to separate waste products?

Vacuoles

The correct answer is Option (4) - Vacuoles

In animal cells, the membrane-bound cell organelles that are generally smaller and help to separate waste products are: Vacuoles

Vacuoles are membrane-bound organelles found in animal cells, although they are typically smaller and less prominent compared to those found in plant cells. While vacuoles in plant cells often serve storage and structural functions, animal cell vacuoles are primarily involved in the storage and transport of molecules, including waste products. They can sequester and isolate waste materials, helping to maintain cellular homeostasis by preventing the accumulation of harmful substances in the cytoplasm. Vacuoles in animal cells may also play roles in regulating pH, storing ions, and facilitating cellular processes such as endocytosis and exocytosis.
