What we will do Today
• Comparing Cells and
Function
• Cell City Analogy
Comparing
Cells and
Function
VOCABULARY
• Prokaryotic Cells – Cells that
contain no nucleus
– Example: Eubacteria and Archaebacteria
Example Prokaryotes
Bacteria Colony
Staphylococcus
VOCABULARY
• Eukaryotic Cells – Cells that contain
a nucleus and membrane bound
organelles
– Examples: Protists, Fungi, Plants, Animals
Example Eukaryotes
Fungus
Amoeba
Animal
Cell Parts – Page 42
Form
Function
Cell Wall
• Support, protection, helps cell maintain shape
Centriole
• Assist in cell division
Chloroplasts
• Captures sunlight to make food for the plant
Chromatin
• Genetic material (as it appears during interphase)
Chromosome
• Genetic material (as it appears during cell division)
Cilia
• Moves fluid over a cell
Cell Parts – Page 42
Form
Function
Cytosol
(cytoplasm)
• Fills space between organelles; contains materials
needed by the organelles
Cytoskeleton
• Helps give shape to the cell involved in movement
Flagellum
• Helps move cell through fluid
Golgi Body
• Modifies and packages materials created in the
cell for transport (inside or outside of the cell)
Lysosome
• Breakdown materials in the cell
Cell Parts – Page 42 & 43
Form:
Function:
Microvilli
• Absorption and secretion
Mitochondrion • Converts sugars to ATP (useable energy)
for the cell
Nuclear
membrane
• Barrier between nuclear material and
cytoplasmic material
Nucleolus
• Makes ribosomes
Nucleus
•Directs cells activities, contains the genetic
material (DNA) of the cell
Cell Parts – Page 43
Form:
Function:
Plasma
membrane
• Barrier between cell and environment, allows
materials to pass into and out of cell, maintains
biological balance
Ribosome
• Produce protein
Rough ER
• ER with ribosomes, helps transport newly made
proteins to Golgi Body
(endoplasmic
reticulum)
Smooth ER
(endoplasmic
reticulum)
• Makes lipids
Cell Parts – Page 43
Form:
Function:
Vacuole
•Stores materials (water) inside the cell
Vesicle
• Stores substances inside cell
Index
Cards
Index Card Examples
• Your group will be assigned 3 – 4 cell
structures
• On the front of the index card:
– Give the name of the structure
– Description of structure
– Drawing of structure
• On the back
– Give the name of the structure
• Yes, this is not a mistake…do it again!
– List the functions of the structures

“IN”
Objective:
What is a function of the cell membrane in all Through note-taking and a
cells?
cell analogy activity, I will
demonstrate how cell
structures relate to function
“OUT”
Four of six kingdoms are comprised
(made) of organisms that contain
eukaryotic cells. Which structures in a
cell would give you the best
evidence that a cell is eukaryotic?
