Laboratory Activities and Assignment

Part 1: Cell Structures

1. Draw an animal cell in the space below. Draw the components of the cell using different colors. Color the parts of an animal cell using a color scheme you developed or on other words, match the color with the cell structure. Use a different color for each of the cell components if possible. Your cell will contain the following structures each labeled on the drawing:

plasma membrane
cytoplasm
nucleus
nuclear envelope
nuclear pore
nucleolus
chromatin

rough endoplasmic reticulum
smooth endoplasmic reticulum
Golgi body
mitochondria
lysosome
peroxisome
vesicle / vacuole

cytoskeleton
centrosome
microvilli
flagellum
cilia
ribosomes

2. Label the 3D model of a cell below with the terms listed. Some structures in this model appear as closed 3D structures (as they would be in a living cell) and others appear as sliced flat (as they would be if we were observing these structures using an electron microscope (TEM, specifically). The colors in the model are significant. Everything that is orange for example is all the same type of structure, but it just may be shown in 3D versus sliced and therefore appears very differently in different spots on the model. Also, vesicles/vacuoles, peroxisomes, and lysosomes are very difficult to tell apart visually only, so don't stress about which one is which.

plasma membrane
cytoplasm
nucleus
nuclear envelope
nuclear pore
nucleolus

chromatin
rough endoplasmic reticulum
smooth endoplasmic reticulum
Golgi body
mitochondrion
lysosome

peroxisome
vesicle / vacuole
centrosome
microvillus
ribosomes

Cell model has leader lines to label the various structures of the cell.

Part 2: Observe, Illustration, and Label Cells of Different Types

Examine the images below of some of the more than 200 different cell types in the human body. Each image has a circle, rectangle, or other marker to indicate what a single cell of this cell type looks like. A few other labels are also included. Use these images for reference in this activity. Also note the scientific terms for different cells often include "-cyte" in their names (e.g. erythrocyte, adipocyte, etc.), which means "cell." So next time you come across a word you don't know that ends in "-cyte," you know that it is a type of cell.

Microscopic images of skeletal, adipose, blood, and cartilage tissues. Each tissue type is labeled to indicate an individual cell and additional structures are also labeled.

For each of the cell types listed below:

Examine a slide with the microscope to observe this cell type.
Identify a single cell in the sample.
Illustrate a single cell from the sample in the space provided below.
Indicate the total magnification (objective magnification x ocular magnification) used to observe and illustrate the cell.
Label your illustration of the cell type with the structures listed for each.
