AP Biology - Cell Organelles

Front

Cell Membrane

Back

The protective outer layer that controls what enters and leaves the cell.

Front

Nucleus:

Back

Stores information on DNA molecules / Directs and controls the activities of the cell.

Front

Endoplasmic Reticulum (ER)

Back

A folded membrane that moves materials around inside cells / Also acts as the site of manufacturing proteins needed by the cell.

Front

Vacuole

Back

A small sack that stores water and food until the cell needs it / Stores waste temporarily until the cell gets rid of it.

Front

Mitochondrion

Back

Bean-shaped organelle filled with folded membranes / Breaks down glucose to release energy for cell functions

Front

Lysosome

Back

Contains digestive hydrolytic enzymes that get rid of waste, worn-out cell parts, and captured invaders.

Front

Ribosomes

Back

non membrane bounded organelles responsible for protein synthesis; found in eukaryotes and prokaryotes

Front

Prokaryotic cell

Back

a cell that lacks a nucleus and other membrane bound organelles; includes archaea and bacteria

Front

Eukaryotic Cell

Back

a cell containing a nucleus and other membrane bound organelles

Front

Cells with many ribosomes specialize in producing which molecules? Options: glycogen, cellulose, proteins, lipids

Back

proteins
