Diversity of Cell Structure and Function
Dr. Ingrid Waldron, Department of Biology, University of Pennsylvania, 20111
1. Complete the table to list three structures in the plant cell which are not found in animal cells
and explain why each of these structures is useful for plant cells, but not for animal cells.
Structure found
in plant cells, but not
in animal cells
1
Why is this structure useful for
plant cells?
Explain why this structure is not
needed or would be a
disadvantage for animal cells.

2. Eukaryotic and prokaryotic cells have some of the same components, but also some different
components. Use the diagrams of the eukaryotic animal cell and the prokaryotic bacterial cell to
show each component from the following list that is found in each type of cell:
cell wall, endoplasmic reticulum, Golgi apparatus, mitochondria, nucleus,
plasma membrane, ribosomes.
Show at least one place where each of the following molecules is found in the eukaryotic cell
and the prokaryotic cell:
ATP, DNA, protein enzyme, phospholipid.

Prokaryotic Bacterial Cell
3. Different types of cells in our bodies have different functions, and they often have different
types or amounts of organelles to accomplish these different functions. The first column of the
table gives some examples. Complete the second column to explain how the specific organelles
or other characteristics of each type of cell help this type of cell to accomplish its function.
Cell Type and
How These Characteristics Help This Type of Cell
Special Characteristics
Accomplish Its Function
Each sperm cell has a
flagellum and very little
cytoplasm.
Pancreas cells that secrete
protein digestive enzymes
have lots of rough ER and
Golgi apparatus.
Phagocytic cells that "eat"
bacteria have lots of
lysosomes and can move
around the body.
Red blood cells have no
nucleus or mitochondria;
red blood cells are filled
with hemoglobin.
