Gives the cell shape, structure and helps it move
Made of: Microfilaments Intermediate filaments
Microtubules
CYTOSKELETON
The “goo” that surrounds the nucleus
Keeps everything in place
Organelles are suspended in cytoplasm
CYTOPLASM
Ribosomes•Structure-spheres composed of RNA and protein
•Function-site of protein synthesis
•Free ribosomes make proteins that remain inside the cell
•Attached ribosomes make proteins that become part of the cell or are exported from the cell

Found in what type of cell??Function:
1. Control headquarters for the cell.
2. Structure:
• Where is the nucleus found
• Contains the genetic material-chromosomes- made of DNA & proteins
• Surrounded by a double membrane-nuclear envelope/membrane
• Inside is a nucleolus that makes ribosomes
AKA… the
________??
Nucleus
??
ENDOPLASMIC RETICULUMROUGH
Structure: Network of membranes
near nucleusWhy is it considered
rough??
Function: Transports proteins that were made by the attached ribosomes through the cell to the golgi.
ENDOPLASMIC RETICULUMSMOOTH
Structure:
Network of folded membranes throughout cell
Why is it considered
smooth??Function:
Makes lipids and breaks down toxic substances.
GOLGI APPARATUS
Location In the cytoplasmStructure
Closely stacked, flattened membrane sacs
Function Stores, packages, and
transports products inside for use outside
Vesicles (a bit of the golgi pinches for transport of stored materials).
LYSOSOME (NOT FOUND IN PLANTS)
Structure-
Saclike
What does the lysosome contain?? Function-
Digests food particles
Digests old organelles
MITOCHONDRIA (FOUND IN ALL EUKARYOTIC CELLS)
Structure-OvalInside is a complex matrix of folded membranes. To
increase surface area.
Function-Changes energy stored in food into a more useful
formMitochondria produces what important energy
storing molecule??
VACUOLE
Location cytoplasm Structure
sac of fluid surrounded by a membrane
FunctionSites of storage of water, ions and some nutrients.
Plants: allows plants to maintain turgor pressure, holds water to prevent wilting.
What would be the role of the large central vacuole
in osmosis??
CHLOROPLAST.
Where is the Chloroplast
found???Structure
Double phospholipid bilayer. Inner layer
Stacks = grana Non stacked area = stroma
FunctionCapturing radiant energy and
converting it to chemical energy. WHAT IS THE NAME OF THE PIGMENT RESPONSIBLE FOR THE GREEN COLOR IN A CHLOROPLAST??
CELL WALL
Locationsurrounding Plant cells
Structurecontains polysaccharide cellulose
FunctionProvides structure and support
for plant cells
____________ are found only in Plant cells. They take in light energy and store it in carbohydrates during photosynthesis.
Note the cell wall and central vacuole in this diagram of a plant cell. They are also found only in plant cells.
The function of the vacuole is????Why is the cell wall important to the plant cell??
