Aim#23: How can we describe the
structure and function of cell
organelles?
1) ORGANIZATION

CELLS
EUKARYOTIC CELLS
ANIMAL CELL
PLANT CELL
PROKARYOTIC CELLS
BACTERIA
Prokaryotes (review)
◦All Bacteria
◦They DO NOT have membrane bound
organelles.
◦They DO have:
◦Cell Membranes
◦Cell Walls
◦DNA
◦Ribosomes
2 Types of Eukaryotic Cells:
◦ Animal Cell
◦ Plant Cell
◦ Both are complex, but there are
differences
2) What are those things inside the
cell?
◦ Organelles- Specialized structures in cells that
perform important cellular functions.
3) What are the eight life functions?
NUTRITION
a) _________________________obtain and processing of food for energy
TRANSPORT
b) _________________________absorption and distribution of materials
RESPIRATION
c) _________________________converting energy stored in food to a usable
form (ATP)
EXCRETION
d) _________________________get rid of metabolic wastes
SYNTHESIS
e) _________________________building larger molecules from smaller ones
REGULATION
f) _________________________control and coordination of life activities
GROWTH
g) _________________________to increase in cell size or cell number
REPRODUCTION
h) _________________________producing new individuals

4a) CELL MEMBRANE
(AKA: Plasma Membrane)
FUNCTION:
◦Barrier to protect the cell.
◦Controls what comes in and out.
4b) CYTOPLASM
FUNCTION:
To protect and support the
organelles within the cell.
•
•Where chemical reactions take place
4c) NUCLEUS
◦ Found in eukaryotic cells only!
◦ FUNCTION:
◦ Controls most cell processes and
contains the hereditary
information - DNA (THE
BRAIN)
◦ Nucleolus◦ Where ribosomes are made
4d) ENDOPLASMIC RETICULUM
FUNCTION:
◦ Transportation route of cell.
Materials travel through it.
◦ 2 Types:
◦ Rough ER (has ribosomes)makes proteins
◦ Smooth ER- makes lipids
and steroid hormones
4e) RIBOSOMES
FUNCTION:
◦ They SYNTHESIZE proteins
◦ Can be found in cytoplasm or on
Endoplasmic Reticulum (Rough)
4f) GOLGI
BODY/COMPLEX/APPARATUS
FUNCTION:
◦ Proteins from ER come here.
Modifies and packages the proteins,
gives them a direction to follow.
4g) MITOCHONDRIA
FUNCTION:
◦ Powerhouse of the cell
◦ Where cellular respiration occurs
◦ Makes energy (ATP) from food and
oxygen.
LYSOSOMES
FUNCTION:
◦ Contain hydrolytic digestive enzymes that can
break down nutrients. Also they break down
dead organelles. (Intracellular digestion)
VACUOLES
FUNCTION:
◦ Store materials
◦ MANY SMALL ONES IN
ANIMAL CELLS, AND
ONE BIG ONE IN PLANT
CELLS.

Aim #23: How can we describe the structure and function of cell
organelles??
Do Now: Identify the organelle that carries out the following
functions…
1) Controls what enters the cell.
2) Controls and regulates the cell (contains DNA)
3) Where most chemical reactions take place.
4) Site of protein synthesis
5) Site of cellular respiration
6) Stores materials

CENTRIOLES
FUNCTION:
•
Involved in animal cell division
•FOUND ONLY IN ANIMAL CELLS
CHLOROPLASTS
FUNCTION:
◦ Use energy from sunlight to
make energy-rich food
molecules (glucose) in a process
known as PHOTOSYNTHESIS
◦ Contains the pigment
chlorophyll
◦ FOUND IN PLANT CELLS!
CELL WALL
FUNCTION
: support and
◦ Provides
protection for the cell.
◦ FOUND IN PLANT
CELLS
CILIA & FLAGELLA
FUNCTION
◦ Aid in: the movement of
individual cells
◦ Flagellum- long tail to
swim
◦ Cilia- lots of little
“hairs” all over the cell

Aim #23: How can we describe the structure and function of cell
organelles??
Do Now:
1) Name three organelles in plant cells that are not in animal cells
and identify the function of each.
2) Name one organelle that is in an animal cell and not a plant cell
and identify its function.
3) Organelles are small structures within cells that help the cell to
maintain _____________________.

1.
2.
I am a concept based on the work of several scientists. I have three parts.
Cell Theory
We are the basic units of structure and function of all living things.
3.
Cells
I provide protection and support. I am made of cellulose and can be found in
plant cells.
Cell Wall
4.
I am the clean up crew. I digest old cell parts.
5.
Lysosomes
We are the tiny structures that make up cells. There are several of us.
Organelles
6.
I am found inside the nucleus.
DNA (genetic information)
7.
I am a clear, thick, jelly-like substance. I am found between the cell membrane and
the nucleus.
Cytoplasm
8.
9.
We are produced in the nucleolus, we make proteins and are found in the cytoplasm.
Ribosomes
I am the process that plants use to make their food. I need chlorophyll in order to
occur.
Photosynthesis
10. I am the “highways” of the cell.
Endoplasmic Reticulum (ER)
11. I am responsible for the passage of material into and out of the nucleus. Nobody
enters or leaves without my permission.
Nuclear Membrane
12. I control all of the activities of the cell. I have been called the brains of the entire
operation.
Nucleus
13. I guard the cell from intruders. I decide who enters the cell and who leaves. I am
present in BOTH plant and animal cells.
Cell Membrane
14. We are known as the “powerhouse” of the cell. We make energy in the form of
ATP.
Mitochondria
15. I am a non-living material making up cell walls. I am stiff and strong, a form of
starch.
Cellulose
