Pre-Lab Questions
Before beginning the virtual microscope lab, it is important to review some key concepts related to microscopy and cell structure. Answer the following questions to check your understanding:
1. What is a microscope?
A microscope is a scientific instrument that is used to view objects that are too small to be seen with the naked eye. It magnifies the image of the object, allowing for detailed examination of its features and structures.
2. What are the two main types of microscopes?
The two main types of microscopes are light microscopes and electron microscopes. Light microscopes use visible light to illuminate the specimen, while electron microscopes use a beam of electrons to create an image.
3. What are the differences between a compound microscope and a stereo microscope?
A compound microscope is used to view thin, transparent samples and is commonly used in biological research. It uses multiple lenses to magnify the image of the specimen. On the other hand, a stereo microscope, also known as a dissecting microscope, is used to view larger, opaque samples with three-dimensional detail. It provides a lower magnification but allows for a wider field of view.
4. What are the main parts of a microscope?
The main parts of a compound microscope include the eyepiece, objective lenses, stage, condenser, and light source. The eyepiece is where the viewer looks into the microscope, while the objective lenses are responsible for magnifying the image. The stage holds the specimen, and the condenser focuses the light onto the specimen. The light source provides illumination.
5. What are cells? Describe their basic structure.
Cells are the basic units of life. They are microscopic in size and can only be seen using a microscope. The basic structure of a cell includes a cell membrane, cytoplasm, and a nucleus (in eukaryotic cells). The cell membrane acts as a barrier, controlling the movement of substances in and out of the cell. The cytoplasm is the jelly-like substance that fills the cell, and the nucleus contains the genetic material of the cell.
Take a moment to review these concepts before proceeding with the virtual microscope lab. Having a clear understanding of these key concepts will help you make the most out of the lab experience and accurately interpret the images you observe.

They used the virtual microscope to magnify and examine different types of cells, tissues, and organisms. This allowed them to identify key features and structures, and record their observations in the lab worksheet.
Observation 1: One of the specimens observed was a plant leaf cross-section. Students were able to observe the different layers of the leaf, including the upper and lower epidermis, palisade mesophyll, and spongy mesophyll. They also noticed the presence of stomata on the surface of the leaf, which appeared as tiny openings.
Observation 2: Another specimen observed was an animal tissue sample. Students identified the presence of cells in the tissue, and noted their specific characteristics. They observed different types of cells, such as muscle cells and nerve cells, which had distinct shapes and structures. The students also observed the arrangement of cells within the tissue, which varied depending on the type of tissue.
Data Analysis: After making their observations, students were required to analyze their data and draw conclusions. They compared the structures and characteristics of different specimens, and identified any similarities or differences. For example, they may have noticed that plant and animal cells have some similarities in structure, such as a nucleus and cytoplasm, but also have distinct differences, such as the presence of a cell wall in plant cells.
