The Cell Theory
Class expectations:
Find Your seat – Be at Zero Level
 Update Your Agenda
 The Vocab Builder is our In-Class Work
for Today.
 Attempt to answer all you can. Then
you can use a text book to find the
other definitions.

Flash Back Wednesday – Find Your Seat,
Go to Zero Level. Write the question and
answer.
1. The cell organelle that can be compared to Mrs.
West because it directs all activities in the cell like
a principal directs activities in a school is the
A. Lysosome
B. ribosome
C. Nucleus
D. mitochondria
2. The jelly-like substance that fills the space
between the organelles labeled in the diagram is
called
A. jelly
B. cytoplasm
C. plasma
D. cytopullium
Some Random Cell Facts
The average human being is composed
of around 100 Trillion individual cells!!!
 It would take as many as 50 cells to
cover the area of a dot on the letter “i”

What is a cell?
 What
is a cell?
 A cell is the basic unit of living
things.
 Some living things are composed of
only one cell and are called
UNICELLULAR organsims.
 Organisms that have many different
cells are called MULTICELLULAR
organisms.
Organelles
Organelles are structures that enable
the cell to live, grow and reproduce.
You will need to know the following organelles
and their function:
Cell Membrane, Nucleus, Cytoplasm
,Mitochondria, Golgi Complex,
Ribosomes,Smooth Endoplasmic Reticulum
Rough Endoplasmic Reticulum, Cell Wall,
Chloroplast, Central Vacuole, Lysosome,
Microtubles, Microfilaments,
Nucleolus,Vesicles,Cytoskeleton,Centrioles
Cell Membrane

Every cell is enclosed
by a cell membrane.
It controls the
passage of materials
in and out of the cell.
Cytoplasm
(not an organelle
All organelles
reside (live
and float
around in)
the
cytoplasm.
 Cell process:
 Cell division

Nucleus

The control center of
the cell. It contains
the DNA code for the
cell coiled into
chromosomes.
 Cell
process: cell
division, protein
making, energy ,
etc
Nucleolus
 Organelle
in the
nucleus that is
the site to make
ribosomes.
 Cell process:
protein making
Chromosomes
Organelles - Store, clean,
support
 Vacoules,
Vesicles,
cytoskeleton,
microtubules,
microfilaments,
centrioles,
lysosomes,
cytoplasm
Lysosome
Breaks down
materials for
digestion.
 Contains special
enzymes for
digestion in the cell.

Flash Back Thursday – Find Your Seat, Go
to Zero Level. Write the question and
answer.
1. Substance X has just entered the cell and begins
to wreak havoc inside. What cell organelle was
responsible for allowing it to enter?
A. Lysosome
B. Ribosome
C. Endoplasmic Reticulum
D. Cell Membrane
2. The cell organelle in a plant cell that could be
compared to a restaurant because it makes “food,”
would be
A. the vacuole.
B. the nucleus.
C. the lysosome.
D. the chloroplast.
Central Vacuole
(Plant Cell Only)
Most plant cells have
one large one.
 Filled w/ fluid.
 Helps maintains
turgor pressure and
shape of cell.

Centrioles
Produces the
microtubules that
pull apart
chromosomes
during cell division
 Cell Process: cell
division

Vesicles
Capsules
that carry
cell
nutrients,
waste, or
water.
Protein Building
Organelles:
ribsosome,
ER(smooth and
rough)
 Golgi appartatus

Ribosomes





Synthesizes proteins.
Present in the cytoplasm.
Present with Rough ER.
No membrane present.
Cell process: protein
making
Smooth Endoplasmic Reticulum
Transports materials
throughout the cell.
 Digests lipids.
 Cell process:
Produces proteins.

Rough Endoplasmic Reticulum
Covered with
ribosomes.
 Cell process:
Produces proteins.
 Transports materials
throughout the cell.

Golgi Complex
The protein
packaging and
transport center of
the cell.
 Has incoming and
outgoing vesicles.

Energy Capture

Organelles:
Mitochondria,
chloroplast
Mitochondria
This organelle
processes energy for
a cell. It makes
ATP.
 (ATP = energy)
 Involved in cellular
respiration.
 Cell process: cellular
respiration

Chloroplast
(Plant Cell Only)





Contains chlorophyll.
Makes plants green.
Uses light energy to
make ATP & sugars.
Photosynthesis takes
place here.
Cell process:
photosynthesis
Boundaries
Organelle:
 Cell membrane
 Nuclear membrane
 Cell wall

Cell Wall
(Plant Cell Only)
Rigid and strong
wall.
 Protects and
maintains the shape
of the cell.

