Vacuole
Golgi
Apparatus
 Bodies of all organisms are made of cells.
 Without cells there is no life.
 Double layer of lipids with
proteins for cell activity.
 The proteins are receptors, pores,
and enzymes.
 Lipid layer (phospholipids) is a
water-fearing molecule.
 Responsible for controlled
entry/exit of substances
Drawing of a cell membrane
 Brain of the cell.
 Controls all parts of the cell
and its functions.
 A membrane-bound
organelle. (Dbl mbrn)
 Communicates using nuclear
pores.
 DNA is found here.
 Prominent structure is the
nucleolus.
 Nucleolus produces ribosomes & RNA
The cell nucleus
 Provide cell with energy through
respiration.
 Double membrane-bound
organelles.
 Outer mmbrn smooth
 Inner mmbrn twisted with cristae (folds)
 On the cristae, sugar combines
with O2 to form ATP (energy
source).
Nuclear Power Plant
Golgi bodies
 Single membrane-bound
structure.
 Packaging and shipping of a
cell.
 Packages are fluid-filled &
called vesicles.
 Vesicles transport large
molecules in cells.
 Site of protein synthesis.
 Read code found in RNA.
 Assemble proteins cell’s need
for growth and different
functions.
Ribosome pic
 Connects outer nuclear membrane
with the cell membrane.
 Function as channels within the cell.
 Two types: Smooth and Rough.
 Smooth are for fat and membrane protein production.
 Rough have ribosomes on its surface and synthesize other
proteins
Endoplasmic reticulum
 Membrane organelles that
store substances.
 Vacuoles move substances in
and/or out of the cell.
 Movement in or out of the
cell is down by fusing with
the cell membrane.
Vacuole
Vac uole
Cell Wall
 Have 2 or more organelles
than the animal cell:
 Cell Wall
 Chloroplast
 The vacuole is larger in plant
cells
Chloroplast
Ribosom e
Endoplasmic
Retic ulum
Nuc leus
Golgi
Apparatus
 Used to support the plant.
 Made of fiber called
cellulose.
 Cellulose is not digested by living organisms
(COLON CLEANSE!)
 Connected to cell membrane
Plant Cell Wall
 Site for photosynthesis
 Photosynthesis is when
sunlight, H2O, and CO2 are
use to make glucose and
oxygen
 Chlorophyll is a green
pigment found here.
 Chlorophyll collects the sun’s
energy.
