The document outlines the key organelles found within plant and animal cells and their functions. It describes the cell membrane, cell wall, nucleus, cytoplasm, endoplasmic reticulum, ribosomes, Golgi bodies, mitochondria, plastids, vacuoles, and lysosomes. The nucleus controls most cell activities and contains DNA. The mitochondria produce energy for the cell and are abundant in muscle cells. Plant cells contain organelles like chloroplasts and vacuoles not found in animal cells.

1. Cell Membrane Outer boundary of cell Protects the cell Controls what enters and leaves the cell

2. Cell Wall Only found in plant cells Adds protection and support Made of cellulose. Allows water and dissolved substances to pass through.

3. The Nucleus Controls most activities in the cell Contains all genetic information in the form of DNA.

4. Cytoplasm Clear fluid within cell that contains all organelles Moves materials throughout the cell

5. Endoplasmic Reticulum Series of folded membranes that form sacs or tubes Rough ER has ribosomes attached

6. Ribosomes Transports materials between the cytoplasm and nucleus Makes proteins in the cell May be free in cytoplasm or attached to ER Proteins are vital to life- all cells must produce them

7. Golgi Bodies Saclike membranes used for storing/ packaging of chemicals Cells that make saliva or mucus have many Golgi bodies

8. Mitochondria Energy producers Powerhouse of the cell Sausage-shaped Many mitochondria in muscle cells

9. Plastids Only found in plants/ algae Contain food or pigments Leucoplasts store food Chloroplasts contain the pigment chlorophyll

10. Vacuoles Store food, water, or waste materials Plant cells have large vacuoles

11. Lysosomes Found in Golgi bodies Contain digestive enzymes to digest unwanted particles Help white blood cells to destroy bacteria
