1. Comparing Organelles to Body Systems

2. Cell Wall A stiff wall surrounding the cell membrane of a plant cell needed for protection Responsible for the shape/support of the cell Body System? Skeletal Protects organs and gives organism its shape/support

3. Cell Membrane A protective barrier between the cytoplasm and outside of the cell Controls what enters and leaves the cell Body Systems? Integumentary System (Skin) Protects against invaders and also controls what enters and leaves an organism’s system.

4. Cytoplasm Gel-like fluid in which organelles are supported Transports materials within the cell Body Systems? Circulatory transports materials around the body

5. Nucleus The control center of the cell and directs all cell activities Body Systems? Brain and Central Nervous System Controls most body functions

6. Mitochondria Mitochondria breaks down nutrients to release energy using oxygen (cellular respiration) Body Systems? Digestive Breaks down food into molecules used by an organism for energy release

7. Golgi Body Packages and sends out proteins Body System? Digestive Breaks down food and repackages it into tiny molecules for body cells

8. Ribosomes Manufactures proteins and sends them to the parts of the cell where they are needed Body System? Digestive Takes in food and converts it into needed molecules

9. Lysosomes and Vacuoles Lysosomes break down cell parts and remove wastes Vacuoles Store waste and necessary materials Body System? Excretory Removes waste from body cells

10. Endoplasmic Reticulum Transports material from one part of the cell to another Body System? Circulatory Transports material around the entire body
