Lab #17 – The Cell and its Organelles

Problem

How do plant cells differ from animal cells?

Hypothesis

  

Materials

3 zip-loc bags

Gelatine

Water

Frozen vegetables

  

Procedure 

Animal Cell

1. Pour the gelatine mixture (cytoplasm) into the plastic bag. 
2. Add the cauliflower (nucleus) and mixed vegetables (organelles), but not the green beans!
3. Draw a picture and label your cell in your results.

Plant Cell

1. Pour the gelatine mixture (cytoplasm) into the plastic bag.
2. Add the cauliflower (nucleus) and mixed vegetables (organelles), including the green beans (chloroplasts).
3. Put the plastic bag cell (cell membrane) into another plastic bag (cell wall).
4. Draw a picture and label your cell in your results.

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