Unicellular OrganismsEntire organism is made up of one single cell
Bacteria and protists
Smallest unit capable of all life functions

Multicellular OrganismsThe organism is made up of many
cells
Cells have specialized functions within the organism

This is maintaining the normal conditions inside of their bodies.
Respond and adapt to their environment

Homework
Go home and find 5 pictures of living things and 5 pictures of non-living things.
Either out of a magazine, real photos or you can even draw them.
Bring them to class and be prepared to share with the class whether they are living things or non-living things and why.
