► Investigation One Summary – Lab Goals
In Investigation One, you observed the variables that should be considered when viewing microscopic specimens such as presence, type of staining, and section preparation. You also noticed that cells from different organisms often appear similar under the microscope. During this Investigation, you:
1. Viewed (6) six unknown specimens under the 4x, 10x, 40x, and 100x oil immersion objectives.
2. Observed differences in cell size, shape, organization, and structure.
3. Reviewed the calculation of total magnification:
Total Magnification = eyepiece (10x) X power of objective
► Investigation One Summary – Learning Goals
Through these experiments, you concluded that:
1. It is unlikely to identify what type of organism a cell comes from through observation. Without a significant amount of prior knowledge, a person may have difficulty drawing conclusions based on what cell structures can or cannot be viewed under a microscope. It is even sometimes difficult to differentiate between unicellular and multicellular organisms.
