The cell is the smallest living unit in the human body, and all cells need specific parts to function. Some of these parts are called organelles. Today you will learn the name of each organelle, and what role it plays in a cell. You will also learn about other materials in a cell, and what jobs they perform.
Let?s start from the outside and work inward. The outer wall of an animal cell is called the cell membrane. It is called a membrane because certain materials can pass through it and into or out of the cell. Plant cells do not have cell membranes. They have cell walls, which do not allow material to move in and out.
