Click on the school bus and take a virtual cell tour!!
Start with the nucleus:
1.
What does the nucleus do?
2.
What happens in the nucleolus?
Next go to the Endoplasmic Reticulum,
first click on the smooth ER.
3.
How is the smooth ER different from the rough ER?
Now go to the Rough ER.
4.
What do the ribosomes on the Rough ER do?
Find a mitochondrion and click on it.
5.
have?
How many layers does the mitochondrial membrane
6.
Mitochondria have their own DNA.
How do scientists
think that
the first Eukaryotic cells came to be?
Now click on a chloroplast.
7.
What happens in the chloroplast?
Next click on the centrioles.
8.
What type of cell (plant or animal?) has centrioles?
9.
What do lysosomes do?
The lysosome is in the upper right part of this cell.
10.
Click on one.
What is autolysis?
Now look at the cell membrane and click on it.
11.
How many layers is in the cell membrane?
Go back to the main page and click on the textbook.
Go to chapter 3, Cell Biology.
Click on the cell membrane again.
Go to the second page and look at the large picture of the cell
membrane.
12.
Why do you think a cell membrane is called a
phospholipid bilayer?
Go to the next page.
13.
What does hydrophilic mean?
What does hydrophobic mean?
Go to the next page.
14.
What are the three types of proteins in the cell
membrane?
