3.5: Laboratory Activities and Assignment

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.

chromatin rough endoplasmic reticulum smooth endoplasmic reticulum Golgi body mitochondrion lysosome

peroxisome vesicle / vacuole centrosome microvillus ribosomes

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.

For each of the cell types listed below:

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

Skeletal Muscle Cell (Muscle Fiber)

Label the cell with: nucleus, striations

Adipose Cell (Fat Cell or Adipocyte)

Label the cell with: nucleus, fat-containing droplet

Red Blood Cell (Erythrocyte)

Label the cell with: n/a (lacks a nucleus)

White Blood Cell (Leukocyte)

Label the cell with: nucleus

Cartilage Cell (Chondrocyte)

Label the cell with: chondrocyte, nucleus, lacuna (a space surrounding the cell)
