7-2 Eukaryotic Cell Structure

Objectives Recognize cells both increase in number and

differentiate, becoming specialized in structure and function, during and after embryonic development.

Describe the structure of cell parts found in different types of cells and the functions they perform.

Explain physical and chemical interactions that occur between organelles as they carry out life processes.

Can I do This??? Identify and describe cell structures and

functions. Define organelles by their functions.

Eukaryotic Cell Analogy

Comparing the Cell to a Factory Organelle= “little

organ” Found only inside

eukaryotic cells! Everything in a

cell except the nucleus is cytoplasm.

Expert Groups!!! FROM HERE, YOU WILL PRESENT THE INFORMATION

FOR NOTES! A – Lysosomes K – Ribosomes Q – Nucleus J – Endoplasmic Reticulum (rough and smooth) 10 – Cell Membrane 9 – Mitochondria 8 – Golgi Apparatus 7 – Cytoplasm/Cytoskeleton 6 – Vacuole 5 – Cell Wall 4 - Chloroplasts

Answer in Your Notes!!!

1) What is the organelle’s function?

What page and paragraph/section did you find this in?

2) What analogy do your group come up with in order to help remember the function of your organelle?

3) What is at least one other interesting fact about your organelle?

When You Are Done Being an Expert Your questions/answers need to be approved

by Mr. Cramer. Once they have been approved, you can begin

your work on the Animal Cell Coloring WS.

Objectives Recognize cells both increase in number and

differentiate, becoming specialized in structure and function, during and after embryonic development.

Describe the structure of cell parts found in different types of cells and the functions they perform.

Explain physical and chemical interactions that occur between organelles as they carry out life processes.

Can I do This??? Identify and describe cell structures and

functions. Define organelles by their functions.

Nucleus Analogy:

“The Control Center”

“The Boss” “The Mayor”

Function: Contains DNA and controls the cell. DNA is the coded

instructions for making proteins.

Ribosomes Analogy: “Factory

Machines” Function: Site of

protein synthesis. Found both on rough

ER and throughout the cytoplasm.

Endoplasmic Reticulum Analogy: “Highway

of the cell” Function: Site

where proteins/lipids are assembled and delivered through the cell. Rough ER: studded

with ribosomes; it makes proteins

Smooth ER: no ribosomes; it makes lipids

Golgi Apparatus

Analogy: “The Mailroom” “UPS”/ ”Fed-Ex”

Function: Modifies, sorts, and packages materials for transport inside/outside the cell.

Lysosomes Analogy:

“Clean-up Crew” “Janitors” (Custodial

Technician) Function:

Breakdown materials so the cell can use them.

Breakdown useless organelles and dispose of them.

Contain strong digestive enzymes.

Mitochondria Nickname:

“The Powerhouse” Function: Creates

energy from the food you eat. Has it’s own strand of

DNA. Almost all

mitochondria comes from the cytoplasm of the egg cell (all mitochondria came from your mom).

Stoppage & ClosureSummaryWrite in complete sentences:

In your opinion, what is the most important organelle to the success of the cell, we’ve covered so far, and what is its function.

Can I do This??? Identify and describe cell structures and

functions. Define organelles by their functions.

Cell Membrane Analogy:

“Door Man” “Gate”

Function: Controls what enters and leaves cell.

Thin flexible barrier.

Cytoskeleton Analogy:

“Steel Beams” Function: Gives

cell structure and shape.

Network of fibers that run through cytoplasm. Gel substance that

makes up cell.

Vacuole Analogy:

“Storage Container” “Warehouse”

Function: Stores materials such as water, salts, proteins, and carbohydrates. Large central vacuole

in plant cells. Many smaller vacuoles

in animal cells.

Cell Wall Analogy:

“Walls” Function: Strong

supporting layer around membrane that gives cell shape. Only in plant cells.

Chloroplasts

Analogy: “Solar Panels”

Function: Traps energy from the sun to produce food for the plant. Contains the

green pigment chlorophyll.

Can I do This??? Identify and describe cell structures and

functions. Define organelles by their functions.

Summary & Closure Any questions for the

good of the cause? When are organelle

projects due???

Summary on BackWhat is the purpose of the organelles found only in plant cells?

Can I do This??? Describe the path a protein takes as it is

manufactured by the cell. I can describe the path of a lipid as it is

manufactured by the cell.

Some Important Vocabulary Protein – molecule needed by the body for

growth, repair, and to create important enzymes.

Lipids – molecule used in cell membrane, includes fats and oils. Both are made from elements such as hydrogen,

carbon, nitrogen, and oxygen.

The Journey of a Protein Using the and the 7-2 notes (it’s the table with

all of the organelles), identify which cards are involved the production, transfer, or delivery of a protein.

Nucleus Rough ER Smooth ER

Mitochond-ria

Lysosomes

Golgi Apparatu

s

Ribosomes

Released From Cell

The Journey of a Protein Path of a Protein:

1. Ribosome2. Rough ER3. Golgi Apparatus4. Export from cell or

to the appropriate organelle

The Journey of a Lipid Path of a Lipid:

1. Smooth ER2. Golgi Apparatus3. Sent for use in cell

membrane or other organelles.

Closure What is due

tomorrow??? SummaryWrite in Complete Sentences

In sentence form, describe the path of a protein from its creation, to export in

the cell.
