Comparing Plant and Animal Cells

19. Animal Cells from the Cheek
Using a toothpick, you can scrape some cells off the inside of our cheeks.  You can imagine how often the skin on the inside of your cheeks rubs against your teeth -- whenever you move your mouth!  Every time you move your mouth, a few cheek cells (called epithelial cells) rub off and you swallow them. 
Stained cells using a chemical called methylene blue

20. Plant Cells from the Elodea
A floating, flowering plant common in ponds that has leaves that are only two cells thick!  The green specks are chloroplasts, which are the little packets inside the cells containing chlorophyll
(molecule that converts sunlight + carbon dioxide + water into sugar) 

21. Characteristics
Plant Cell
Animal Cell
Cell Size
Large
Smaller than plant cells
Cell Shape
Rectangular
Circular
Vacuoles
A single centrally located vacuole. It takes up almost 90% of the cell volume. The vacuole stores water.
If any, there are a number of small vacuoles spread throughout the cytoplasm that store water, ions and waste materials.
Cell Wall
Present
A rigid cell wall made of cellulose helps plant maintain shape.
Absent
This allows animal cells to adopt different shapes.
Chloroplasts
Chlorophyll is the pigment that traps sun's energy which is utilized by plants to make food through the process of photosynthesis. This pigment is present in the chloroplasts.
As animals lack this pigment, they cannot make their own food.
Lysosomes
Vesicles that contain enzymes that destroy dead cell organelles and other cells debris.
Golgi Bodies
In place of golgi bodies, its sub units known as dictyosomes are present.
Complex Golgi bodies are present close to the nucleus.
