Membrane
Cytoplasm
DNA
 When
you think about a membrane,
imagine it is like a big plastic bag with
some tiny holes.
 That bag holds all of the cell pieces and
fluids inside the cell and keeps any nasty
things outside the cell.
 The holes are there to let some things
move in and out of the cell.
 Selectively permeableonly allowing some things
to pass in and out
 Is
not one solid piece. Everything in life is
made of smaller pieces and a membrane is no
different.
 Compounds called proteins and
phospholipids make up most of the cell
membrane.
 The phospholipids make the basic bag.
 The proteins are found around the holes and
help move molecules in and out of the cell.
 As
you travel through the cell membrane
and enter the cell, you will find yourself
floating in a kind of jelly, this is the
cytoplasm.
 Cytoplasm helps to hold the cell's
organelles or “small organs” in place.
 Gives
the cell structure. Think of a balloon.
An empty balloon does not have much
structure. However, if we fill it with
something, like water, it begins to take
shape.
 Cytoplasm also helps the cell move proteins,
chromosomes and other materials, including
the cells organelles, around the cell.
 DNA
is like the instruction manual of a
cell.
 It comprises of a long string of code
which tells the cell what type of cell it has
to be and what functions it must perform.
 Index
Card
 Yarn
 Macaroni
 Glue
 Are
what you think of when you think of a
classic "cell."
 They are cells with an organized nucleus.
 All living organisms on Earth are divided in
pieces called cells. There are smaller pieces
to cells that include proteins and
organelles.
 Acts
like the brain of the cell.
 It helps control eating, movement, and
reproduction. If it happens in a cell, chances
are the nucleus knows about it.
 The nucleus is not always in the center of the
cell. It will be a big dark spot somewhere in
the middle of all of the cytoplasm.
 City Hall
 Long
molecule containing hereditary
information that directs the cell’s
functions and the organisms
development.
 City Documents
 The
ER is the site of protein and lipid
production.
 Factory
 Are
the protein builders or the protein
synthesizers of the cell.
 Cells need to make proteins. Those proteins
might be used as enzymes (increase rate of
chemical reactions) or as support for other
cell functions.
 Complexes that use DNA copies to build
proteins
 Factory Workers
 Packages
and modifies proteins, then
send them off to their destinations.
 Works closely with the Rough ER
 Post office
 Acts
as a semi-permeable barrier that
lets certain things pass into and our of the
cell.
 Protection and support for the cell.
 City Limits
 Known
as the powerhouses of the cell.
 They are organelles that act like a digestive
system that takes in nutrients, breaks them
down, and creates energy for the cell.
 Uses oxygen and food molecules to
generate useful energy for the cell.
 Power Plant
 Uses
sunlight, carbon dioxide, and water
to produce glucose and oxygen through
the process of photosynthesis.
 Food producers of the plant cell.
 Every green plant you see is working to
convert the energy of the sun into sugars.
 Restaurant
 Stores
water, salts, and nutrients
 Storage bubbles found in cells.
 They are found in both animal and plant
cells but are much larger in plant cells.
 Reservoir
 Digests
or breaks down waste, old cell
parts, viruses and bacteria.
 Recycling center
 Hair-like
structures wave to move a cell
around, or to move something around the
cell.
 Can keep dust, smog, and potentially
harmful microorganisms out
 Every
animal cell has two small organelles
called centrioles.
 They are there to help the cell when it comes
time to divide.
 You will usually find them near the nucleus but
they cannot be seen when the cell is not
dividing.
 The centrioles are made of Microtubules.
 Help
define cell structure and movement
 Are thick, strong spirals of thousands of
subunits. Those subunits are made of the
protein called tubulin.
 And yes, they got their name because
they look like a tube.
A
small round body of protein in a cell
nucleus.
 The main function of the nucleolus is to
produce and assemble the ribosome
components.
 The
fluid that fills a cell.
 Mix of molecules, proteins and small cell
parts.
 Chemical reactions occur here.
 Cell
walls are made of specialized sugars called
cellulose.
 Paper is made of cellulose.
 Cell walls also help a plant keep its shape.
 While they do protect the cells, cell walls and
cellulose also allow plants to grow to great heights.
 It's like taking a water balloon and putting it in a
cardboard box. The balloon is protected from the
outside world.
