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.

Objectives

 

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.cture and Function
