CELLSStructures and Functions

(organelles and jobs)

CELL MEMBRANESurrounds and protects the cellControls what gets in and out of

the cell

Gateway to the cellDoor

CYTOPLASMLiquidy substance inside every

cell – the environment of the cellFlows or streams

Gelatin (Jello)

NUCLEUSDirects all activities in the cellContains the instructions for everything a

cell does

DNA is inside the nucleus – chemical that has the codes/instructions

Brain of the cell

MITOCHONDRIARelease energy from food that is

eaten

Powerhouse of the cellMit = mighty/power

RIBOSOMESMake the proteins needed by the

cell

Manufacturing Plant – assembly line

ENDOPLASMIC RETICULUM

Moves materials around inside the cell

Cell’s highway or roads or canal

Golgi bodiesSort and package substances

within the cellMove materials to the cell

membrane to be eliminatedTaxiMoving Company

LYSOSOMESRecycle worn out products within

the cell

Recycling center

VACUOLEStores water, waste products,

food, and other materials

Storage shed – holding tank

Cell wallTough, rigid outer covering that

protect the cell and give it shapeOnly found in plant cells, fungi

and bacteriasupport = brick wall

chloroplastsContain green pigment called

chlorophyll-which gives plant its green color

Captures sunlight to make sugar by process of photosynthesis

cellsTwo types of cells:1. Eukaryotic –have a nucleus and

other organelles

2. Prokaryotic –have NO nucleus, have cell membrane and ribosome, that’s it.
