Unit
Plan
Unit Title: Cell Structure and Function
Subject: Biology
Grade: 9th
State Standard
Number 1.0: Cells
The student will investigate the structures and functions of cell
membranes, organelles, and component biomolecules as
related to major cell processes.
Unit Rationale
Without a thorough understanding of cells, the basic units of all
living things, much of what is studied in the biological sciences would not
make sense. This unit introduces students to the cell. They will explore the
events leading to its discovery and examine cell organelles and their
respective functions.
Goals
1. TSW explore
the discovery, classification, specialization and organization of cells.
2. TSW recognize
internal cell structures and their functions.
3. TSW assess the
significance of cell boundaries and their associated activities.
TSW explore
the discovery, classification, specialization and organization of cells:
1. TSW state the cell theory
2. TSW compare prokaryotes and eukaryotes
3. TSW define cell specialization
4. TSW list the (4) levels of organization in multicellular organisms
TSW recognize
internal cell structures and their functions:
5. TSW label the parts of a cell
6. TSW match cell organelles with their
respective functions
TSW assess the
significance of cell boundaries and their associated activities:
7. TSW name the (2) cell boundaries and
summarize the role of each
8. TSW differentiate between diffusion and
osmosis
9. TSW distinguish between facilitated diffusion
and active transport
10.
TSW name (5) types of active transport
Instructional
Procedures
1. TTW outline
the history of the cell, provide classifications, define cell specialization
and illustrate the levels of cellular organization through a PowerPoint
presentation.
2. TSW complete a
venn diagram to make a comparison between prokaryotic
and eukaryotic cells. This assignment will be completed using Microsoft Word
and emailed to the teacher.
3. TSW construct
an analogy to explain how the levels of organization in a chosen area in their
lives (i.e. school, sports, etc.) can be compared with those of living
organisms.
4. TTW identify
the parts of a cell and their associated functions through a PowerPoint
presentation.
5. TSW compare a
cell to their school and use that analogy to describe the parts of a cell and
their functions. This assignment will be completed using Microsoft Word and
emailed to the teacher.
6. TSW complete
the Eukaryotic Cell Interactive Animation activity found at http://www.cellsalive.com/cells/cell_model.htm.
7. TTW examine
cell boundaries and their related activities through a PowerPoint presentation.
8. TSW create a
concept map about the ways substances can move into and out of cells using
Microsoft Word and send completed assignments to the teacher via email.

Addressing
Student Needs
This unit addresses a variety of student needs. First, this unit
caters to both the visual learner, through the venn diagram, concept maps and CELLS alive! activity, and one that
prefers the written word, through the PowerPoint presentations. Second, those
students suffering from a learning disability that causes low motivation and/or
short attention span will be able to view the PowerPoint presentations at their
own pace and review them as many times as needed in order to ensure that they
fully grasp the material. Next, assignments will be completed using Microsoft
Word in order to accommodate those students who have a writing disability.
Finally, the teacher is available to answer questions on an individual basis
through email.
