Lab #8 – The Cell and its Organelles

Lab #8 – The Cell and its Organelles

Problem

How are plant cells and animal cells both similar and different?

Hypothesis

Materials

3 zip-loc bags

various slime ingredients

Procedure 

Animal Cell

1. Pour the slime mixture (cytoplasm) into the plastic bag (cell membrane). 
2. Add the  styrofoam sphere (nucleus) and  the clay pieces, plastic squares and pasta (organelles), but not ANY GREEN!

Plant Cell

1. Pour the slime mixture (cytoplasm) into the plastic bag (cell membrane).
2. Add the styrofoam sphere (nucleus) and  various clay pieces and pasta (organelles), including the green clay/squares (chloroplasts).
3. Put the plastic bag cell into another plastic bag (cell wall).

Results

Animal Cell	Plant Cell

  

Analysis

1. Compare/Contrast your plant and animal cells.

2. Predict what would happen to a plant cell if it were to lose its chloroplasts.

3. Explain the importance of the nucleus in both cells.

4.       On your gel cells, what is representing the cell membrane?  How is the cell membrane like your skin?

5.     5. What would happen if your cells lost their cytoplasm?  What would the cell look like?

 *Cell Model Project*  Create your own model of an animal and/or a plant cell.  What materials would you use?  Make a list of what is going to represent the following: cytoplasm, cell membrane, nucleus, organelles, cell wall (plant cell only), chloroplasts (plant cell only).
