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

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).
