protein
Depending on the part of the cell various combinations of: lipids, proteins, carbohydrates, nucleic acids, glycerine, salts/esters, water, etc.
In a sense rRNA, tRNA, and mRNA are all used in the translation of the genetic code to make proteins which are most of what a cell is. But in general, nucleic acids just contain the genetic blueprints of a cell.
A good analogy for an animal cell's parts is to think of the cell membrane as the "gatekeeper" controlling what enters and exits like a security checkpoint at a stadium. The nucleus can be compared to the "control center" that contains the cell's genetic information like a CEO in an office. Mitochondria are like the "power plants" producing energy for the cell, and the endoplasmic reticulum is like the "manufacturing warehouse" where proteins are made and processed before distribution.
Two parts of the cell that can be used for movement and are made by the cytoskeleton are cilia and flagella.

It depends on what kind of cell it is. For example, a plant cell will have a cell wall. Therefore, an animal cell will not have that. Although, both of them have a cell membrane, nucleus, nucleolus, endoplasmic reticulum, DNA, and many other parts. Cells are very detailed and are the building blocks to life.
DNA
I labeled all the cell parts in my drawing.Drawing the cell parts, I understood plant cells better.Once I understood cell parts, I wanted to be a scientist.
Well, the unique cell parts in a protists are the flagella and the pseudopod. Only protists have flagellas and pseudopods. They are both used to move.
