LEVELS OF

ORGANIZATION

HOW IS LIFE
ORGANIZED?

• Life is organized into

different levels based upon
size (small to large).

• As we move up each level,

the level of complexity
increases.

TYPE OF TISSUE

• Connective Tissue: the tissue that holds

things together and supports other tissues
(Bone, Blood).

• Epithelial Tissue: the tissue that provides

covering (skin, lining of organs)

• Muscle Tissue: helps move the skeleton.

• Nervous Tissue: used to carry messages

all over your body to your brain.
