 Activity 38: Microbes, Plants and You        

 

     Scheiden, Schwann, and Siebold observed plants, animals, and microbes.   Since then, scientists have observed cells in every living organisim.  What do these cells look like?

 

1. View and Draw and Onion Plant Cell --- Plant Cell  (follow directions in text book)

 

2. View and Draw a Cheek Cell --- Animal Cell (follow directions in text book)

 

3. View and Draw an Amoeba Cell --- A microbe (follow directions in text book)

 

4. View and Draw an Green Leaf Plant Cell --- A microbe (follow directions in text book)

 

Answer Analysis 1-6

ANALYSIS 1. Compare the three kinds of cells you have just observed. 

a.  What structures do they have in common? Explain. 

b.How are the cells different? Explain. 

2.Look at the Venn diagram you drew at the beginning of the activity. 

Make any additions or changes now that you have observed plant and animal cells 

with microscope. 

3. Did you find evidence in this activity that the human body is made up of cells?Explain. 

4. You stained the onion cells. How did the cells look before and after staining?

 Explain the purpose of the stain. 

5. Do you think there are any small structures(organelles) inside the cell other than the nucleus?

 What evidence do you have to ­cheek support your answer?6. Do you think there are any small structures (organelles) inside the plant cells, 

either the onion or the green plant cell, other than the nucleus?

What evidence do you have to support your answer? 

 

 

 

6. Draw, Label and Color a Plant Cell and an Animal Cell
