Yes, Some Have The Same Body Cells Some Have Different Body Cells.
Humans store excess polysaccharides in the form of glycogen.
Polysaccharides are carbohydrates. They are generally used to generate energy in the form of ATP for the body's metabolic activities.
Carbohydrates are broken down during respiration to generate energy. Excess carbohydrates are generally converted to glycogen through the actions of an enzyme in the liver.
Glycogens are converted back to simpler carbohydrates when there is inadequate carbohydrate in the body.

"Specialized" organelles or parts means that these parts have been modified to carry out a specific function that is unique to them.
Organelles are literally "little organs" and each of them in the cell has a specific and distinct function.
For example the nucleus is an organelle. It is arguably the most important organelle in the cell. Its specific overall function is that it acts as the cell control center, directing the activities of all the other organelles .i.e. what they need do and when to do it.
The nucleus also contains all of the cell's genetic material (DNA).
