The basic unit of structure and function in living things.

Front

Prokaryote

Back

A unicellular organism that lacks a nucleus and membrane-bound organelles; example: bacteria.

Front

Eukaryote

Back

A cell that contains a nucleus and membrane-bound organelles; examples include plant and animal cells.

Front

Chromatin

Back

DNA that is unraveled so it can be accessed to help cell function; under a microscope, it appears as granular material visible within the nucleus.

Front

Chromosomes

Back

Thick structures made of DNA molecules that contain genes; condensed chromatin for cell replication.

Front

DNA

Back

Deoxyribonucleic acid, a self-replicating material present in all living organisms as chromatin or chromosomes. It carries genetic information.

Front

Nucleus

Back

Control center of the cell; contains DNA.

Front

Nuclear membrane

Back

Membrane that surrounds the nucleus.

Front

Cell membrane

Back

A cell structure that controls which substances can enter or leave the cell.

Front

Endoplasmic reticulum (ER)

Back

The transportation system of the cell. It moves materials around inside the cell.
