1. Organization of Cells in Living Things – Ch. 7-3

2. Unicellular vs. multicellular
Uni = one celled organism
Examples: bacteria, protozoa, many algae and some fungi.
Multi = many celled organism
Examples: humans, cats, dogs, plants, and spiders.

3. Tissues Groups of cells organized for a specific function.
Examples: epithelial, connective, adipose, bone, cartilage, blood, nerve, and muscle.

5. Epithelial Tissue
Cover the body surfaces and line cavities and organs.
Examples: skin and glands.

6. Connective Tissues Support and bind tissues and organs together
Examples: bone, tendons, and ligaments.
Tendons = muscle to bone
Ligaments = bone to bone

8. Muscle Tissues Specialized for contraction and shortening. 3 types
Smooth = stomach, intestine, blood
Skeletal = attach to bones for movement
Cardiac = heart

9. Organ vs. Organ Systems Organ = groups of tissues together
Organ System = groups of organs together (Ex. Shoot System – plants)
