Tuesday – Sept. 20, 2011“IN”What is a function of the cell membrane in ALL cells?

Objective:Through note-taking and a group index card activity, I will compare and contrast prokaryotic and eukaryotic cells as well as the functions of their structures

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 ProkaryotesExample Prokaryotes

StaphylococcusStaphylococcus

Bacteria ColonyBacteria Colony

VOCABULARY• Eukaryotic Cells – Cells that

contain a nucleus and membrane bound organelles– Examples: Protists, Fungi, Plants, Animals

Example EukaryotesExample Eukaryotes

AmoebaAmoeba

AnimalAnimal

Cilia

FunctionFunction• Support, protection, helps cell maintain shape

• Assist in cell division

• Captures sunlight to make food for the plant

• Genetic material (as it appears during interphase)

• Genetic material (as it appears during cell division)

• Moves fluid over a cell

Cytoskeleton

Flagellum

Golgi Body

Lysosome

FunctionFunction• Fills space between organelles; contains materials needed by the organelles

• Helps give shape to the cell involved in movement

• Helps move cell through fluid

• Modifies and packages materials created in the cell for transport (inside or outside of the cell)

• Breakdown materials in the cell

Nuclear membrane

Nucleolus

Nucleus

• Absorption and secretion

• Converts sugars to ATP (useable energy) for the cell

• Barrier between nuclear material and cytoplasmic material

• Makes ribosomes

•Directs cells activities, contains the genetic material (DNA) of the cell

Ribosome

Rough ER(endoplasmic reticulum)

Smooth ER(endoplasmic reticulum)

Function:Function:• Barrier between cell and environment, allows materials to pass into and out of cell, maintains biological balance

• Produce protein

• ER with ribosomes, helps transport newly made proteins to Golgi Body

• Makes lipids

Vacuole

Vesicle

•Stores materials (water) inside the cell

• 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

Tuesday – Sept. 20, 2011“IN”What is a function of the cell membrane in all cells?

Objective:Through note-taking and a 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?
