Prokaryotic Cells – NO
Organelles
BACTERIAL CELL
Organelles
Cells all have certain functions
 Organelles help the cell carry out it’s
specific role
 Organelles - separate parts of the cell
that carry out essential cell processes.
Each organelle has a unique structure
and function.
 Organelles in the notes are highlighted
in RED

ANIMAL CELL
Structure and Organelles – Animal
Cells Only!
Centrioles – occur in pairs and aide in cell
division
 Lysosome – contains digestive enzymes
that breakdown excess or worn-out
cellular substances

PLANT CELL
Structure and Organelles – Only
Plant Cells!
Cell Wall – non-flexible barrier that
provides support and protects the plant
cell
 Chloroplast – contains chlorophyll where
photosynthesis takes place
 Vacuole – vesicle for temporary storage of
water and food

Support Structures


Cytoplasm – fluid
material inside the
cell in which all
organelles are
located
Cytoskeleton –
framework for the cell
within the cytoplasm
Nucleus
Contains coded
instructions for the
production of proteins and
cell division
 Nucleolus - The round
structure within the
nucleus of a cell
composed of protein and
RNA
 Nuclear Membrane
(envelope) - The doublelayered membrane
surrounding the nucleus
of a eukaryotic cell,
separating the nucleus
from the cytoplasm

Endoplasmic Reticulum and
Ribosomes




Endoplasmic
Reticulum – site of
protein and lipid
synthesis
Ribosomes –
produce proteins
Smooth ER –
contains NO
ribosomes
Rough ER –
contains ribosomes
Mitochondria

Produces energy for
the rest of the cell
Golgi Apparatus


Modifies proteins
and packages them
for shipment out of
the cell
Think of it like UPS
or the postal service

Cilia
 Short, numerous
projections that look
like hairs
400x
Flagella
 Longer and less
numerous than cilia
 Create movement
with a whiplike
motion
26,367x

Complete the chart using your textbook and the
purple cell book on my bookshelf
• Use page 199 of your book!
DO NOT complete the channel, receptor and
marker section of the chart today!
• We will do this later this week
Be sure your work is of quality. This is worth some
major points!
