Labs/Assignments: Critical Thinking, Chapter Worksheets,Tissues Lab
Topic Outline: Cells and Tissues
I. Overview of the Cellular Basis of Life:
4 Primary Elements Common to All Cells
II. Anatomy of a Generalized Cell:
Cell (plasma) Membrane
The cell membrane has four basic functions; how does a cell perform?
Critical Thinking 3.1: The cytoplasm of a cell is different in its composition than the extracellular
fluid (the fluid outside the cell) what structure maintains this difference? How?
Critical Thinking 3.2: Compare a single generalized cell to our human body, each of these
organelles may be somewhat analogous (similar to) to a system in the body. For each organelle,
above, list a body system that the organelle is similar to.
III. Cell Physiology
Passive Transport Process
Define and provide an example and draw a picture of the following:
Critical Thinking 3.3: Read “A Closer Look” on p.64. What happens to a red blood cell placed in a
hypertonic, hypotonic or isotonic solution? Why?
Active Transport Process
Define and draw a picture of Active Transport
Bulk Transport Processes
Define and draw a picture of the following:
Phagocytosis (kind of like ….)
Critical Thinking 3.4: Why do we need the ability to actively transport solutes?
Critical Thinking 3.5: There are two basic purposes of mitosis, describe how mitosis facilitates
Growth of the organism
Replacement of dead or damaged cells
Critical Thinking 3.6: Functions of Cells- Describe how a cell performs the following vital
Critical Thinking 3.7: Can a cell maintain homeostasis? What is the meaning of the term
homeostasis? Are there situations in which a cell cannot regulate homeostasis and therefore is
unable to function properly and possibly dies? Please describe two such situations.
IV. Body Tissues:
List and describe the basic function of the four basic types of body tissues
V. Epithelieal Tissues:
Where is epithelium located?
Describe the five special characteristics of epithelium
Critical Thinking 3.8: Epithelium has four basic functions-give an example of how epithelium
performs each of these functions:
Critical Thinking 3.9: When our skin is slightly cut or scratched, why do we not bleed? How deep
must the cut or scratch be in order for us to bleed? Why?
Epithelial Tissues: Complete the table
Type Description Picture Where Found
VI. Connective Tissue
List the 5 types of Connective Tissue along with their subtypes
Critical Thinking 3.10: What is the most commonly thought of “loose connective tissue”? Which
connective tissue would you least likely have thought of as a tissue? Why?
VII. Muscle Tissue
Characteristics of Muscle Tissue: Complete the table
Type Location Structural Features General Functions Nervous Control
Critical Thinking 3.11: What is the basic function of Muscle Tissue?
VIII. Nervous Tissue
What are the 2 basic functions of nervous tissue, what does this mean?
Where is nervous tissue located?
IX. Tissue Repair
Critical Thinking 3.12: Which type of tissue heals the “best healer”? Why? Which type of tissue
is the ”worst healer”? Why?
X. Developmental Aspects of Cells and Tissues
Critical Thinking 3.13: Look back at Critical Thinking 3.10, which term from this section explains
why some tissues heal well and others do not? Why?
