Eukaryotic Cell Parts & Their Jobs

Eukaryotic cell Type of cell that contains many tiny organs called organelles Usually grouped together with many other cells that are similar – multi cellular

The Cell Organelles Function to keep the cell alive Click next to see them all individually

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

Cell Wall Only found in plant cells (& some bacteria and algae) Adds protection and support Made of cellulose. Allows water and dissolved substances to pass through.

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

Cytoplasm Clear fluid within cell that contains all organelles Moves materials throughout the cell Provides many raw materials for chemical reactions

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

Ribosome's 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

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

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

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

Vacuoles Store food, water, or waste materials Plant cells have 1 large vacuole

Lysosomes Found in Golgi bodies Contain digestive enzymes to digest unwanted particles
