Cell Basics
A cell is the very smallest unit of living matter.
All living things including plants and animals are made up of cells.
Cells are made of atoms, which are the smallest units of matter.
There are many different kinds of cells.
Cell membrane: surrounds the cell, holds the other parts of the cell in place, and protects the cell.
Nucleus is a dark structure located in the middle of the cell. It controls the cell's activities, and acts like the cell's brain.
Cytoplasm is a jelly-like substance inside the cell where most of the cell's activities take place.
