Nucleus

Stores DNA and controls cell activities.

Cell Membrane

Controls what enters and leaves the cell.

Cytoplasm

Holds organelles and is where many chemical reactions occur.

Mitochondria

Produce most of the cell's ATP, which provides usable energy.

Ribosomes

Make proteins.

Golgi Apparatus

Modifies, sorts, and packages proteins and lipids.

Lysosome

Contains digestive enzymes that break down materials.

Cell Wall

Gives plant cells support and protection.

Chloroplast

Performs photosynthesis in plant cells.

Prokaryotic Cell

A cell without a nucleus.

Eukaryotic Cell

A cell with a nucleus and membrane-bound organelles.

DNA

Genetic material that contains instructions for cell activities.

Organelle

A specialized structure inside a cell that performs a specific function.

Plant Cell

A eukaryotic cell with a cell wall, chloroplasts, and a large central vacuole.

Animal Cell

A eukaryotic cell without a cell wall or chloroplasts.

Vacuole

Stores water, nutrients, waste, or other materials.
