Sheppard Software Cell Games: ANIMAL CELL (KEY) Part I – Animal Cell Tutorial Directions:   

Go to: http://www.sheppardsoftware.com/health/anatomy/cell/index.htm Under “Animal Cell” click Tutorial. Answer the following questions as you click on the text words appearing in purple.

1. Click on the word “plasma membrane.” This is another term for cell membrane. -What does the website compare the plasma(cell) membrane to? Doorman -Why is this a good comparison? Like a door, it controls what molecules enter and leave 2. Click on the word “ribosomes.” -

-

The website lists two places where you can find ribosomes. Please list both. On ER Floating in the cytoplasm What do the ribosomes make for the cell? Proteins

3. Click on the word “mitochondria.” -

What does the website compare the mitochondria to? Power Plant

-

Why is this a good comparison? They produce ATP which fuels the cells actions

4. Click on the word “nucleus.” -

What does the website compare the nucleus to? Mayor

-

What does the nucleus hold inside of it? Genetic Material (DNA)

5. Click on the word “golgi apparatus.” This is the same as golgi body. -

What does the website compare the golgi apparatus to? Packaging plant

-

Why is this a good comparison? It packages lipids and proteins into vesicles

6. Click on the word “cytoplasm.” -

The website explains two important functions of the cytoplasm. Please list both of these functions. Maintains internal pressure Contains important molecules to help make proteins Assignments

7. Click on the word “lysomsomes & peroxisomes.” -

What does the website compare these organelles to? Recycling stations

-

Why is this a good comparison? They break down wastes and clean up the cell

8. Click on the word “endoplasmic reticulum.” -

Look at this cell part on the diagram. Why does the ER need to be shaped like a long winding maze? Read the information on the website to formulate your answer. HINT: Think about the ER’s function. It prepares proteins for transport to the Golgi so the ER must be a passageway through the cytoplasm

Part II – Animal Cell GAME Directions:  

Click on “Play the Game.” Play the Game by matching the term to the cell part on the diagram.

9. To make sure you played the game correctly. List the correct order of labels starting with plasma membrane and continuing clockwise (this means go around to the right.) Plasma membrane, mitochondria, ribosomes, golgi body, cytoplasm, lysosomes, nucleus, ER

Part III – Animal Cell QUIZ Directions:  

After the game, Click on “Quiz.” Take the quiz by clicking on the organelle that best fits the description.

10. To make sure you take the quiz, please place the correct answers to the questions below. - this organelle contains DNA tightly packed into chromosomes: nucleus - this thin lining controls what molecules enter and leave the cell: plasma membrane - these organelles break down the cell’ waste products: lysosomes and peroxisomes - this network of folds is dotted with ribosomes.: ER - Like a packaging plant, this organelle puts lipids and proteins in vesicles: Golgi Apparatus - this organelle often ships proteins to the Golgi Apparatus: ER - this fluid maintains the internal pressure of the cell and holds nutrients: cytoplasm - these little organelles follow instructions and create proteins for the cell: ribosomes - these organelles produce a molecule called ATP, which is fuel for the cell: mitochondria - this organelle holds the cell’s genetic material: nucleus
