Classroom Teacher Preparation
Anatomy/Physiology 1: Cell City
Please use the following to prepare for the next SfS lesson.
Description:
By competing to construct a model of a cell, students learn about its components and their functions. The analogy of the
cell as a city is used to make the information more understandable to students learning about cells for the first time.
Lesson Objectives – SWBAT (“Students Will Be Able To…”):

•
Understand what a cell is and that cells function similarly in all living organisms
Understand that in multicellular animals, cells make up tissues and tissues make up more complex structures
called organs
Explain cell organelles different jobs and how they work together using an analogy of a city
Explain the characteristics that distinguish plant cells from animal cells, including chloroplasts and cell walls
Preparation:
This module provides a broad overview of the topic, and is best used as an introduction to the subject.
Vocabulary:
These terms will be defined in lesson:
• Cell - the smallest structural and functional unit of
an organism.
• Cell membrane - the semipermeable membrane
surrounding the cytoplasm of a cell.
• Organelle - a specialized structure within a living
cell.
• Cell wall - a rigid layer of polysaccharides lying
outside the plasma membrane of the cells of
plants, fungi, and bacteria.
• Cytoplasm - the material or protoplasm within a
living cell, excluding the nucleus.
• Cytoskeleton - a microscopic network of protein
filaments and tubules in the cytoplasm of many
living cells, giving them shape and coherence.
• Chloroplasts - an organelle found in plants that
contains chlorophyll and in which photosynthesis
takes place.
• Endoplasmic reticulum - an organelle within the
cytoplasm of a eukaryotic cell. It usually has
ribosomes attached and is involved in protein and
lipid synthesis.
• Golgi apparatus - an organelle made of folded
membranes within the cytoplasm of most
eukaryotic cells, involved in secretion and
intracellular transport.
• Lysosome - an organelle in the cytoplasm of
eukaryotic cells containing degradative enzymes
enclosed in a membrane.
• Mitochondrion - an organelle found in large
numbers in most eukaryotic cells, in which the
biochemical processes of respiration and energy
production occur.
• Nucleus - a dense organelle present in most
eukaryotic cells containing the genetic material.
• Ribosome - a minute particle consisting of RNA
and associated proteins, found in large numbers in
the cytoplasm of living cells. Ribosomes bind
messenger RNA and transfer RNA to synthesize
polypeptides and proteins.
• Vacuole - an organelle enclosed by a membrane
and typically containing water or fluid.

Room Set Up for Activities:
Students will work in groups of 2-5 at their desks or tables to complete the cell modeling activity.
Safety:
There are no safety concerns for this lesson.
Related Modules:
This lesson may be taught as part of a sequence or group of related modules on either Cells or Heredity. Other modules
in these sequences include:
Anatomy/Physiology 2: Mitosis - This module teaches the basics of mitosis using plant root tips. Students learn to identify
cells in the different stages of mitosis, as well as how to use a compound light microscope and (for classes with ample
time) prepare a wet-mount slide.
Anatomy/Physiology 3: DNA is Everywhere - This lesson covers some basics of the role of DNA before students extract a
visible sample of the molecule of life from food (strawberries, bananas, or peas).
Anatomy/Physiology 6: Blood Composition and Compatibility - This is an introductory lesson detailing the components of
blood and highlighting the process and importance of blood typing. The lesson starts with an introduction to the cells and
fluids making up our blood, followed by a simulated blood typing activity.

Lessons are matched to both national NGSS and local state standards.
Classroom Post and Activities:
A link to the Follow Up Student activity can be found in the Classroom Post on our website at
sciencefromscientists.org/cohorts. Use the name of your school/cohort and password to log in. Students can explore
virtual cells and learn about the many organelles through an online game.
Additional Resources:
WGBH Videos and Activities: The PBS educational site is a great, free resource for educators but you must create an
account to use the materials. The first time you log in to the PBS Learning Media website you will be asked to create an
account and provide an email and password. Once you have logged in, select “keep me logged in” to avoid having to
repeat the process.
