All living things have cells
All living things have DNA
All living things grow and develop
All living things respond to stimuli
All living things have metabolism

Living Things
All Living Things Have Cells
• A cell is the basic unit of life
• A cell controls all the
activities of the organism
– AN ORGANISM IS ANY LIVING
THING
• A living thing can be
multicellular (lots of cells)
• A living thing can be
unicellular (one cell)

• DNA is a special chemical
inside the cell that controls
all the activities.
• DNA stands for
deoxyribonucleic acid.
• It makes you who you are
(genes).
