Plant Cells vs. Animal Cells
Fill in the Venn diagram below with facts about what plant and animal cells have in common and how they are different.
Plant Cells
Animal Cells
How do bacteria cells compare to plant and animal cells? They are considered to be prokaryotic, while plant
and animal cells are considered eurkaryotic.

Big Thinking Questions (attach extra paper if necessary)
1. Cholesterol is a waxy, strong substance found mostly in the cell membranes of animal cells. Why do animal cells need more of this strong
substance in their cell membranes and plant cells do not? Excess cholesterol in the blood stream in humans can lead to heart disease.
Following a special diet can decrease cholesterol levels. What kind of diet would a doctor suggest for a patient with high cholesterol
levels?
2. The amount of mitochondria in cells varies greatly according to the cell type. Some cells may have only one, and others may have
thousands. Of these 3 types of cells, which one do you think has the most mitochondria: Blood cell, bone cell, muscle cell. What are the
reasons for your answer?
3. Trace the path of a protein as it is produced and travels through the cell. What organelles does it go through?
4. There is compelling evidence that mitochondria and chloroplasts were once primitive bacterial cells. This evidence is described in the
endosymbiotic theory. Symbiosis occurs when two different species benefit from living and working together. When one organism actually
lives inside the other it's called endosymbiosis. The endosymbiotic theory describes how a large host cell and ingested bacteria could easily
become dependent on one another for survival, resulting in a permanent relationship. Over millions of years of evolution, mitochondria and
chloroplasts have become more specialized and today they cannot live outside the cell. What do mitochondria and chloroplasts do that
would make them ideal partners for simpler cells ?
