Cells

The purpose of this lab is to assist you in learning the basic structure and function of cells in both plants and animals. Some cell structures (organelles) are the same amongst plants and animals while some are unique to one or the other.

You will go to the following website: http://www.glencoe.com/sites/common_assets/science/virtual_labs/E08/E08.html

You will follow the instructions and work through the simulation as instructed in the lab. As you click on each organelle, you will use the clues to identify the name of the organelle and the function of the organelle. You will also identify whether it belongs in an animal cell, plant cell or both.

As you perform the simulation, you will record your results in the table below (use another color font for your answers). If a cell type doesn’t contain the cell listed in the table, please indicate NONE in that part of the table.

Once you have completed the lab activity and the table, you will answer the remaining journal questions below. Please answer all questions in another color font.

Save your file as .doc or .docx and upload it into eCampus in the proper lab section for grading. Do NOT copy and paste it into the text box on eCampus.
