Inside a Cell!
Introduction to cell
organelles
Cell Theory Review

Three main points to the cell theory:
All living things are composed of cells
 Cells provide structure and carry on
major functions to sustain life



Organisms (living things) can be single cell
(unicellular) or made of many cells
(multicellular)
Cell function is similar in all living things
What’s inside you?
What’s inside a cell?
Organelles – parts inside of a cell
that have specific functions
Welcome to CLUB CELL!!!
What type of club is it?
Nucleus
 FUNCTION
 Controls
the cell
and contains its
genetic material
(DNA)
Nucleus
 ANALOGY
 The
nucleus is like
the CLUB
OWNER because
they control what
happens in the
club.
Cell Membrane
 FUNCTION
a
semipermeable
barrier of the
cell that lets
materials in or
out
Cell Membrane
 ANALOGY
 The
cell
membrane is
like a
BOUNCER
because it only
lets certain
things in or out
Mitochondria
 FUNCTION
 To
process
nutrients and
oxygen into
energy
Mitochondria
 ANALOGY
 The
mitochondria
are like a DJ
because they play
music to give the
club energy
Lysosome
 FUNCTION
 To
digest and
break down
materials in the
cell
Lysosome
 ANALOGY
 The
lysosomes are
like HUNGRY
PEOPLE. They
have one purpose:
to digest!
Cytoplasm
 FUNCTION
 The
fluid that
fills the cell
Cytoplasm
 ANALOGY
 The
cytoplasm
is like THE
CROWD
during crowd
surfing.
Vacuoles
 FUNCTION
 To
store
materials for the
cell
 Ex:
nutrients,
water, waste, etc.
Vacuole
 ANALOGY
 The
vacuoles are
like CLOSETS.
They can be used
to store many
things.
Endoplasmic Reticulum
 FUNCTION
 To
store,
package, and
move materials
needed to
make proteins
Endoplasmic Reticulum
 ANALOGY
 The
E.R. is like an
“IN” WAITER
because it
packages orders
Ribosomes
 FUNCTION
 To
build
proteins for the
cell and
organism
Ribosomes
 ANALOGY
 The
ribosomes are
like CHEF
because they
combine simple
ingredients to make
complex dishes
(proteins)
Golgi Bodies
 FUNCTION
 Processes
protein
packages and
sends them
where they are
needed
Golgi Bodies
 ANALOGY
 The
Golgi Bodies
are like an “OUT”
WAITER
because they take
the dishes
(proteins) where
they are needed

Main Idea Web
Organisms can be
classified by their
cell type.

Molecular Biology
8.L.5 Understand the composition of various substances as it relates to their ability to
serve as a source of energy and building materials for growth and repair of organisms.
8.L.5.1
Summarize how
food provides
the energy and
the molecules
required for
building
materials,
growth and
survival of all
organisms (to
include plants).
8.L.5.1 Food provides molecules that serve as fuel and building material for
all organisms. Organisms get energy by oxidizing their food, releasing some
of its energy as thermal energy. All organisms are composed of cells-a group
of organelles working together. Most organisms are single cells; other
organisms, including humans, are multi-cellular. Cells carry on the many
functions needed to sustain life. They grow and divide (mitosis or meiosis),
thereby producing more cells. This requires that they take in nutrients, which
they use to provide energy for the work that cells do and to make the
materials that a cell or an organism needs. Cell (Plasma) membrane is
selectively permeable, controlling what enters and leaves the cell. Sugars to
produce energy for the cell are broken down in a process that uses oxygen
and produces carbon dioxide and water. Cells lacking internal membranebound structures are called prokaryotic cells. The cells of most unicellular
organisms such as bacteria are prokaryotes. Cells that contain membranebound structures are called eukaryotic cells. Most of the multi-cellular plants
and animals we know have cells containing membrane-bound structures and
are therefore called eukaryotes. The membrane-bound structures within
eukaryotic cells are called organelles. Each organelle has a specific function
for cell survival.
