Do Now:
• Draw a picture of a cell and
label as many parts as you can.
The Cell
• The parts of a cell
are called?
• Organelles.
• Organelles means
“little organs”
Types of Cells
• Plant cell
Animal cell
The Cell Membrane
• Surrounds the cell
• Allows materials to move in and out
• The Cell Membrane (1min 1sec).asf
Chromosomes
• Made of DNA
• Instructions for building the body
Nucleus
• Contains the Chromosomes
• Found in the center of the cell
• Organelles - The Nucleus (1min 6sec).asf
Nuclear Membrane
• Separates Chromosomes from the
rest of the cell.
Cytoplasm
• Supports the Organelles.
• Many chemical reactions happen here.
• The Cytoplasm (21sec).asf
Just like complex organisms, cells are able to
survive by coordinating various activities.
Complex organisms have a variety of systems,
and cells have a variety of organelles that
work to help the cell survive. Describe the
role of two organelles. In your answer be
sure to include:
• The names of two organelles and the function of
each.
• An explanation of how the organelle does it’s job.
• The name of the organelle and the name of a part
of the human body that has a similar function.
Mitochondria
• Site of cellular respiration
(production of ATP)
• Powerhouse of the cell
• Organelles - Mitochondria.asf
Ribosomes
• Site of protein synthesis (use information from
DNA to make proteins)
• Very tiny
Endoplasmic Reticulum
• Transports materials around the cell
• Network of passageways
• Organelles - The Endoplasmic Reticulum
(33sec).asf
Golgi Body
• Packages materials for export out of
the cell
Centrioles and Spindle Fibers
• Centrioles are anchor point for spindle fibers
• Spindle fibers appear during cell division
Lysosomes
• Contains enzymes that digest foreign
particles and old cell parts
Vacuole
• Storage
space for
food,
water or
waste
products.
Vacuole
Cell Wall
• Protective outer layer on plant cells
• Adds support
Chloroplast
• Contain Chlorophyll
• Site of Photosynthesis
• Chloroplasts and Photosynthesis (50sec).asf
Write down a part of the cell we
learned today that you think is
most important and describe why
you think it is most important.
• Ask a neighbor what they thought was most
important and why.
• Pick ONE.
• Why did you decide to pick that one?

Cell Parts (organelles)
• There are two types of cells that we
are going to be talking about.
• Animals are made up of what type of
cell?
• Answer: Animal cells! (includes
humans).
• Plants are made up of what type of
cell?
• Answer: Plant cells!
Animal Cell
Parts of the Animal
cell
• Part # 1 – The Nucleus.
• The nucleus is the control center
of the cell.
• It contains the chromosomes
which are made of DNA.
Part #2 – The Nuclear Membrane
• The Nuclear Membrane surrounds
the nucleus and keeps the
Chromosomes separate from the
cytoplasm.
Part #2 – The Nuclear Membrane
Part #3 – Chromosomes
• Structure found in the nucleus
that contains hereditary material.
Part #3 – Chromosomes
Part #4 – Centrioles
• Cylindrical
structures only
found in animal
cells that aid in
replication (cell
division).
Part #5 - Mitochondria
• Breaks down food and releases
energy.
• Often called the powerhouse of
the cell.
Part #6 - Cytoplasm
• Gel-like liquid that all of the
other organelles float around in.
• Most of the chemical reactions
that occur in the cell happen in
the cytoplasm.
Part #7 – Cell Membrane
• Protective outer covering of
all cells that regulates what
goes in and out of the cell.
Part #8 - Vacuole
• Space within the cell that can be
used to store food, water or
waste products.
• Vacuoles are the storage
compartments of the cell.
Part #9 – Endoplasmic
Reticulum (ER)
• Network of folded membranes that act as
a transport system for materials in the
cell.
• Can be Rough or Smooth.
• Rough ER – Has ribosomes attached to it.
• Smooth ER – No ribosomes attached to it.
Part #10 - Ribosomes
• This organelle is used to make proteins
within the cell.
• Ribosomes are like the factories of the
cell where small structures (amino acids)
are put together to form larger
structures (proteins).
Parts of the Plant Cell
• Plants have
organelles in
them that
Animal cells
don’t have.
Part #1 - Ribosomes
• This organelle is used to make proteins
within the cell.
• Ribosomes are like the factories of the cell
where small structures (amino acids) are put
together to form larger structures (proteins).
Part #2 – Endoplasmic Reticulum
(ER)
• Network of folded membranes that act as a
transport system for materials in the cell.
• Can be Rough or Smooth.
• Rough ER – Has ribosomes attached to it.
• Smooth ER – No ribosomes attached to it.
Part #4 - Nucleus
• The nucleus is the control center of the cell.
• It contains the chromosomes that are made
of DNA.
Part #3 – Cell Wall
• Rigid structure that encloses, supports and protects
the cells of plants, algae, fungi and most bacteria.
• Cell walls in plants are made of cellulose.
Part #2 – The Nuclear Membrane
• The Nuclear Membrane surrounds the
nucleus and keeps the Chromosomes
separate from the cytoplasm.
Part #6 – Chromosomes
• Structure found in the nucleus that contains
hereditary material.
Nuclear membrane and
Chromosomes
Part #7 – Cell Membrane
• Protective outer covering of all cells that
regulates what goes in and out of the cell.
Part #8 - Cytoplasm
• Gel-like liquid that all of the other
organelles float around in.
• Most of the chemical reactions that occur in
the cell happen in the cytoplasm.
Part #9 - Mitochondria
• Breaks down food and releases energy.
• Often called the powerhouse of the cell.
Part #10 –
Chloroplasts
•
•
•
•
Structures found only in the plant cell.
Site of photosynthesis.
Photo = Light, Synthesis = To make.
So Photosynthesis is to make something (glucose)
using Light!
Part #11 - Vacuole
• Space within the cell that can be used to
store food, water or waste products.
• Vacuoles are the storage compartments of
the cell.
