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.

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)

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!!

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.
