Standard S7L2b:
Relate cells structures (cell membranes, nucleus, cytoplasm, chloroplasts, mitochondria) to basic cell functions
We are made up of microscopic living things called: CELLS
There are Approximately 100 TRILLION cells in the Human Body.
DID YOU KNOW?DID YOU KNOW?
100 Trillion
PLANT CELLANIMAL
CELL
ORGANELLES
structures in the cell
carry out specific functions in the cell
Cells are made up of Different Parts! Each Part has a Specific Function!The Parts:
NucleusMitochondriaCytoplasmEndoplasmic ReticulumRibosomesGolgi ComplexVacuolesLysosomesCell Membrane
THE PARTS OF THE THE PARTS OF THE CELLCELL
-A protective barrier that encloses a cell.
-Separates the cell’s contents from the cells environment.
-Cell Membrane is like a Fence.
CELL MEMBRANECELL MEMBRANE
CYTOPLASMCYTOPLASMGel-like fluid found all throughout the cell. Like Jell-O
Constantly Moving (Swishing around) All Other Parts are Suspended in Cytoplasm!
DNA (our genes) Found here!Acts like the Brain!Directs all of the cell’s activitiesi.e. tells all the other parts what to do!
Houses Nucleolus
THE NUCLEUSTHE NUCLEUS
NUCLEI AND ACTIN FILAMENTS IN CULTURED EPITHELIAL
CELLS
NUCLEOLUSNUCLEOLUS
Found INSIDE the Nucleus!
Powerhouse of the CellBreak down Sugar to Produce all Energy!In the form of ATP
MITOCHONDRIAMITOCHONDRIA
Protein Factory! Smallest of ALL organelles
RIBOSOMESRIBOSOMES
WHERE ARE WHERE ARE RIBOSOMES? RIBOSOMES?
Carry Proteins and other cell materials from one part of cell to another!
Like Roadways! Two Types: Smooth and RoughRough E.R. has RibosomesSmooth E.R. does NOT have Ribosomes!
ENDOPLASMIC ENDOPLASMIC RETICULUMRETICULUM
WHERE ARE THE WHERE ARE THE SMOOTH AND SMOOTH AND ROUGH ER? ROUGH ER?
SMOOTH AND ROUGH ER
A.K.A Golgi ApparatusLike Postoffice
Receives Proteins (mail) from the E.R. Packages them (puts it in envelope)Distributes them to other parts of cell (Mailman)
GOLGI GOLGI COMPLEXCOMPLEX
WHERE IS THE GOLGI WHERE IS THE GOLGI COMPLEX?COMPLEX?
VACUOLESVACUOLES
The Storage Container
Stores food and water
Some Animal Cells have Some Animal Cells have Vacuoles while Others Vacuoles while Others Don’t!!Don’t!!
WHERE ARE THE WHERE ARE THE VACUOLES?VACUOLES?
Janitors of the CellBreak down old cell parts! Release them for recycling

CELL WALLCELL WALL
Plant Cell Plant Cell Only!Only!Rigid, cellulose structure that gives support to a Rigid, cellulose structure that gives support to a
cell.cell.Although made of different materials algae, Although made of different materials algae,
fungi, bacteria, and archaea also have cell walls. fungi, bacteria, and archaea also have cell walls. Like a wall!Like a wall!

CHLOROPLASTCHLOROPLAST
Plant Cell Only!!Makes food for the cell. Chlorophyll traps the sunlight needed to perform
photosynthesis and gives plants their green color.
Like a Restaurant!
