This scientist was the first to identify cells and name them.

All organisms are made up of them.

This is a network of proteins that is constantly changing to meet the needs of the cell. It provides a framework for the structure of the cell.

This isolate and transport specific proteins.

This forms a boundary between a cell and the outside environment and controls the passage of materials into and out of the cell.

This scientist made better microscope lenses and could observe cells in greater detail. He named living cells "animalcules."

All cells are produced by these.

This is the storehouse for most of the genetic information in the cell.

These supply energy to the cell.

A phospholipid is composed of these three parts.

This scientist was the first to note that plants are made of cells.

The cell is the most ______________ of life.

This produces, processes, and transports lipids and proteins.

These temporarily store materials such as water, food molecules, inorganic ions, and enzymes.

This describes the arrangement of the molecules that make up a cell membrane.

This scientist concluded that all living things are made of cells. He made the first draft of the Cell Theory.

Improvements in the ______________ helped scientist develop the Cell Theory.

These link amino acids together to form proteins.

These digest and recycle foreign or worn-out parts.

This term means that some, but not all, molecules are allowed to pass through the cell membrane.

This scientist proposed that all cells come from other cells.

Growing cells in a petri dish relates to this part of the Cell Theory.

These are closely layered stacks that of membrane-enclosed spaces that modify, package, and transport proteins.

These divide DNA during cell division.

This is a protein that detects a signal molecule and performs an action in response.
