Detailed explanation-1: -The cytoskeleton is not organelles. They are proteinaceous structural elements that provide mechanical support and also maintain cell shape. They help in movement, intracellular organization, and cell division.

Detailed explanation-2: -The nucleus is not considered as a part of the cytoplasm as the material contained in the nucleus is separated by the materials of the cytoplasm through the nuclear membrane.

Detailed explanation-3: -Summary. Vesicles store and transport materials with the cell. Some of these materials are transported to other organelles, other materials are secreted from the cell. Examples of vesicles include secretory vesicles, transport vesicles, synaptic vesicles and lysosomes.
