CELL ORGANELLES

• Plant, Animal, and Bacterial

2
CELL WALL
Description Layer of non-living material called
cellulose found on plants bacterial Function Pr
otects the cell. Allows materials to pass
through easily. Helps plants to stand up on
their own
3
Description Thin layer FunctionControls
what substances come in and out of a cell by
passing materials through tiny pores.
CELL MEMBRANE
4
CELL MEMBRANE
Description Thin layer FunctionControls
what substances come in and out of a cell by
passing materials through tiny pores.
5
NUCLEUS
Description Large, oval structureFunctionCon
trol center of the cell that directs all
activities.
6
Description Thin layerFunction Protects
the nucleus by controlling what come in and out
through tiny pores
NUCLEAR MEMBRANE
7
DescriptionThin StrandsFunction Contains
genetic material that directs the functions of
the cell.
CHROMATIN
8
Description Small ObjectFunction Produces
ribosomes
NUCLEOLUS
9
Description Clear, thick, gel-like
fluidFunctionProduces energy, build and
transport needed materials, store and recycle
wastes.
CYTOPLASM
10
Description Rod-shaped structuresFunction
Produces the energy the cell needs to carry out
its functions
MITOCHONDRIA
11
ENDOPLASMIC RETICULUM
Description Maze of Passageways Function Carry
protiens and other materials from one part of
the cell to another
12
Description Small, grain-like
bodiesFunctionFactories that produce proteins
RIBOSOMES
13
GOLGI BODIES
Description Flattened collection of sacs and
tubes Function Receives proteins and other
newly formed materials from the E.R., packages
them, and then distributes to other parts of the
cell
14
CHLOROPLASTS
Description Large green structures found almost
only on plants Function Capture energy from
sunlight and uses it to produce food for the cell.
15
VACUOLES
DescriptionRound, water filled sacfound most
often on plant FunctionProvides storage
16
DescriptionSmall round structureFunctionCont
ains chemicals that break down large food
particles into smaller ones
LYSOSOMES
17
BACTERIAL CELLS
Bacterial cells are much less complicated. They
dont have as many parts and are not very well
organized as plant and animal cells
