Transcript Cell Organelles

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 lifeall 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
