Multicellular Organisms
• In unicellular (single-celled) organisms, the single cell performs all life functions. However … multi-cellular organisms have various levels of organization.
• Individual cells may perform specific functions and also work together for the good of the entire organism.
• Multicellular organisms have 5 Levels of Organization from simple to complex.

Level 1: Cells
• Basic structural unit of living things
• May serve a function within the organism
• Examples: • blood cells, nerve cells, bone
cells ,etc.

Level 2: Tissues
• Made up of cells of similar structure and function and work together to perform a specific function.
• Examples:• Blood, nervous, bone, etc.

Level 3: Organs
• Made up of tissues that work together to perform a specific activity.
• Examples:• Heart, brain, skin, etc.

• Groups of two or more organs that work together to perform a specific activity.
• Examples: • Circulatory system, digestive
system, nervous system, endocrine system, etc.

Level 5: Organisms
• Entire living things that can carry out all living processes.
• Usually made up of organ systems, but an organism can be made up of only one cell such as a bacteria.
• Examples:• Bacteria, mushroom, sunflower,
human, etc.
