genetic
information
present in nearly
all organisms;
forms a double
helix

Mitochondrion
A structure within a cell that is surrounded by a
phospholipid bilayer (cell membrane)
An organelle in the cytoplasm of eukaryotic cells
that functions in energy production; the power
factory of the cell
Nucleus
