characteristics of living things living things have six characteristics in common
TRANSCRIPT
All living things:
• have cells.• sense and respond
to change.• reproduce.• have DNA.• use energy.• grow and develop.
All living things have cells.
• Living things are composed of one or more cells
• Smallest unit that can carry life.
• Living things made of more than one cell have specialized cells.
All living things sense and respond to change
• Stimulus-a change that affects the activity of an organism.

All living things have DNA
• deoxyribonucleic acid
• DNA carries the instructions for an organisms traits.
• Parents pass DNA to their organisms during reproduction.
• The passing of traits is called heredity.
All living things use energy.
• Living things use energy to carry out the chemical activities of life.
• For example;changing energy into food, breaking down food, moving materials into and out of the cell, growing, and building new cells.
