Model of the Animal Cell
Purpose: The purpose of this lab investigation is to study a model of an animal cell and locate structures within it called organelles.
Materials and Methods: For this experiment, the student will need a Ward's model of the animal cell and a key of the cell parts.
Experiment:
Examine the Ward's model of the animal cell and complete the following based on your observations:
1. Locate the large blue central compartment or organelle in the model. This structure is the __________. Examine the membrane that forms this organelle. Two unique features of this membrane are: a. _____________________ and b. __________________________________. There are two white "ball-like" masses within. These are the ____________. The fine red thread-like structures represent the ________________.
2. What color is the cytoplasm on this model? _____________.
3. Locate the orange organelles in the model. These organelles look like _____________________ and are called__________________. The inner folds visible in these organelles are called __________.
4. The blue organelles throughout the cytoplasm
that are highly branched are the _________________. How does the
"rough" one differ from the "smooth" one?
_______________________________________
__________________________________________________________.
5. Locate the small, red "sand-like" structures in the model. What are they? __________________. What two places do you see them? ____________________________________________________.
6. What is the very large red structure in the cytoplasm? It is over near the edge of the cell model. _____________. Describe it as it appears on the model: _____________________________.
7. What are the two "pink" structures on the model? __________________________. Why is each one shown as 9 tubes bundled together? ________________________________________________. Where in the cytoplasm do you see them? That is, what other organelle are they located near? ____________.
8. Compare the model to the illustration
above. What are some cellular components that are not represented on the
model? ________________________________________________________
__________________________________________________________________________________
Conclusion:
What are the features of an animal cell?
