Click on the name of each organelle to learn about its structure and function
Cytoskeleton
To Animal Cell
Centriole
• Barrel-shaped made up of 9 microtubules
• Usually found in only animal cells
• Organizes spindle fibers used during cell division
Back to Animal Cell Back to Plant Cell
Structure Function
Mitochondria
• Double Membrane– Outer is
smooth– Inner cristae is
folded to increase surface area
• Powerhouse of the cell– Site of cellular
respiration– Breaks down
glucose to Produce ATP

Structure Function
Golgi Body
• Stacks of membranes and sacs in cytoplasm
• Packages macromolecules for transport
Back to Animal Cell Back to Plant Cell
Structure Function
Rough Endoplasmic Reticulum
• Vesicles and tubules covered with ribosomes
• Transports proteins made on its surface
Back to Animal Cell Back to Plant Cell
Structure Function
Nuclear Membrane
• Lipid bilayer containing many openings (pores)
• Separates the chromatin from the rest of the cell
• Pores allow material to enter and leave the nucleus

Structure Function
Ribosomes
• “Packets” of RNA.– Made up of a
large and a small subunit
• Site of protein synthesis
Back to Animal Cell Back to Plant Cell
Structure Function
Cell Membrane
• Phospholipid bilayer
• Regulates what enters & leaves the cell
Back to Animal Cell Back to Plant Cell
Structure Function
Smooth Endoplasmic Reticulum
• Vesicles and tubules NOT covered with ribosomes
• Many different functions depending on the type of cell
• Generally – transports large molecules around the cell

Structure Function
Lysosome
• Spherical body in the cytoplasm
• Usually found in animal cells
• Storage of digestive enzymes (for digesting food or worn out cell parts)
Back to Animal Cell Back to Plant Cell
Structure Function
Cytoplasm
• Made up of the cytosol (liquid within the cell) and all of the organelles
• Site of glycolysis (breaking down glucose molecules)
Back to Animal Cell Back to Plant Cell
Structure Function
Chromatin
• “Unwound” chromosomes (DNA)
• Instructions for producing all of the body’s proteins (enzymes)
Back to Animal Cell Back to Plant Cell
Structure Function
Nucleolus
• Spherical body found in the nucleus
• Produces ribosomes
Back to Animal Cell Back to Plant Cell
Structure Function
Nucleus
• Large membrane bound organelle
• Directs cellular activity
Back to Animal Cell Back to Plant Cell
Structure Function
Vacuole
• Membrane bound organelle
• Large in plants and fungi very small or absent in bacteria, protists, or animal cells
• Storage of water, digestive enzymes, wastes and food
Back to Animal Cell Back to Plant Cell
Structure Function
Cell Wall
• Layers of cellulose, pectin and lignin, surrounding plant, bacteria and fungi cells.
• Protection and support
Back to Animal Cell Back to Plant Cell
Structure Function
Chloroplast
• Double membrane spherical body containing structures called thylakoids
• Found in plants and algae
• Site of photosynthesis (glucose production)
Back to Animal Cell Back to Plant Cell
Structure Function
Cytoskeleton
• A network of microtubules and microfilaments
• Support and aid in transport within the cell

Cell Coloring Instructions:
Use the following color coding according to the functions of the cell organelles. Full credit (50 points!) includes:1) Correct coloring, 2) List what each color represents, 3) List of the organelles and their functions.
RED - Energy (Animal: Mitochondria; Plants: Mitochondria and Chloroplasts)
YELLOW - Protein Preparation (Animal/Plant: Golgi, Rough-ER, Smooth-ER, Ribosomes, Nucleolous, Nuclear Membrane).
BLUE - Genetic Information (Animal/Plant: Nucleus, Chromatin)
GREEN - Waste (Animal: Change the Vacuole's name into Lysozome; Plant: Vacuole).
BROWN - Physical Support (Animal: Draw Cytoskeleton elements, such as rods and branches; Plants: Cell Wall).
Cytoplasm, Cell Membrane - are involved in nearly ALL of these processes. Leave uncolored (or add a very light background color).
