Cell Biology Basics

Front

Cell Membrane

Back

The thin, flexible layer around a cell that controls what goes in and out, like a security guard.

Front

Cell Structures

Back

The different parts inside a cell (like organelles) that each do a special job to keep the cell alive.

Front

Cell Wall

Back

A tough, outer layer found in plant cells (and some bacteria) that gives the cell shape and support.

Front

Chloroplast

Back

The green part of plant cells that uses sunlight, water, and carbon dioxide to make food (sugar).

Front

Lysosome

Back

A small structure in animal cells that breaks down waste and old cell parts, kind of like a recycling center.

Front

Mitochondria

Back

The “powerhouse” of the cell; they turn food into energy the cell can use.

Front

Nucleus

Back

The control center of the cell that stores DNA and tells the cell what to do.

Front

Nutrients

Back

Substances like vitamins, minerals, proteins, and sugars that living things need to grow and stay healthy.

Front

Organisms

Back

Any living thing, such as an animal, plant, fungus, or bacteria.

Front

Waste

Back

Materials a cell or organism doesn’t need and has to get rid of, like carbon dioxide or broken cell parts.
