UNIT OVERVIEW and VOCABULARY LEARNING WITH FRAYER MODELS
UNIT 3 Homeostasis and Transport
Unit 3 Cell Homeostasis and Transport
Unit Overview: Cells are the fundamental or basic unit that makes up all living things. Some living
things are unicellular meaning they are made of only one cell. Other organisms are multicellular
meaning they are composed of many, even millions of cells. Although there are many hundreds of
different cell types found in living things, all cells can be placed in one of two categories: prokaryotic or
eukaryotic. Although these two categories of cells have important differences, they also share a number
of cellular similarities. In this unit, we will learn about the differences and similarities between these
two cell types. We will then explore how the special structures unique to eukaryotic cells, called
organelles, function to maintain life for the cell as well as the organism the cells live within. We will also
study the many ways materials are exchanged between the cell and its outer environment through the
plasma membrane. Together, these cell structures, their functions and the interactions between the cell
and its environment work to maintain homeostasis, a balanced living state, within the organism.
Unit Assignments/Assessments:

Unit 3 Exam
Extra Credit/Enrichment Opportunities: Weekly Biochallenges, Constructing a Cell Model (see below)
Create either an animal or plant cell model. All cell organelles and structures discussed in class must be
labelled. On a separate sheet of paper describe the function of each cell organelle/structure. The model
can be constructed from any type of material (foam, clay, noodles, jelly). Enrichment points: 15
Unit 3 Learning Targets:
1. I can compare cellular structures and their functions in prokaryotic and eukaryotic cells.
2. I can describe how membrane-bound organelles (e.g., endoplasmic reticulum, Golgi
apparatus) transport and move materials throughout a cell.
3. I can describe how the structure of the plasma membrane allows it to function as a regulatory
structure as well as a protective barrier for a cell.
4. I can compare the mechanisms that transport materials across the plasma membrane.
Passive Transport: diffusion, osmosis, facilitated diffusion Active Transport: pumps, endocytosis,
exocytosis
