This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing this information in an editable file which can be sent to an instructor.
Purpose
What is the purpose of this exercise?
The purpose of this exercise is to use the microscope to get an in depth look at different cell structures and to learn how the shape and arrangement of different cells can affect their functions.
Are there any safety concerns associated with this exercise? If so, list what they are and what precautions should be taken.
Some safety concerns could be while assembling and moving the microscope it is important to be careful as to not break the microscope. It is a very delicate piece of equipment and should always be handled with two hands when being moved and should always be on a flat surface.
Exercise 1: Epithelial Tissue
Data Table 1: Epithelial Tissue Observations
TISSUE TYPE
OBSERVATIONS
Simple Squamous Flat, scale-like cells, and very close together.
Simple Cuboidal
Single layer of cube/oval like cells, cells are not packed together
Simple Columnar (stomach)
Single layer of different sized tall, narrow cells, connective tissue
Simple Columnar (duodenum)
Columnar cells, brush border, basement membrane, goblet cells, connective tissue.
Stratified Squamous (keratinized)
Multiple cell layers with cells becoming increasingly flat and scaly toward surface
Stratified Squamous (non-keratinized)
Cells long flat cell boarded by a darker layer of cells
Pseudostratified Ciliated Columnar
3 layers of cells; surface cells are round or
