Transcript of Eukaryotic Cell and Organelles

Objective
SWBAT identify the structure and function of the parts of typical eukaryotic cells.
Main Idea
Eukaryotic cells contain organelles that allow the specialization and the separation of functions within the cell.
Cytoplasm
The semifluid material located in the environment inside the plasma membrane.
Cytoskelton
A framework for the cell within the cytoplasm.

It is made up of microtubules and microfilaments.
Nucleus
Control center of the cell that contains most of the cell's DNA.

It is surrounded by a double membrane called the nuclear envelope. This membrane is similar to the plasma membrane as it contains nuclear pores which allow larger-sized substances to move in and out of the nucleus.
Nucleolus
The center-most area within the cell which produces ribosomes.
Ribosomes
Organelle that is the site for protein synthesis.

These organelles do not have a membrane like most others.
Rough Endoplasmic Reticulum
(Rough ER)
A highly folded membrane that is a site for protein and lipid synthesis, covered by ribosomes.

The presence of the ribosomes give the rough ER it's "rough" monicker.
Smooth Endoplasmic Reticulum
(Smooth ER)
A highly folded membrane that is a site for protein and lipid synthesis, free of ribosomes.

The absence of the ribosomes give the smooth ER it's "smooth" monicker.
Golgi apparatus
A flattened stack of membrane that modifies proteins and packages them for distribution outside the cell.
Lysosomes
Vesicles that digest excess or worn-out organelles and food particles.
Mitochondria
Helps to make usable energy available to the cell from fuel particles like carbohydrates.
The Eukaryotic Cell and its Organelles
Exit Ticket
1. Which organelle is responsible for providing the energy for the cell?

2. Where is the genetic material located in the cell?

The absence of the ribosomes give the smooth ER it's "smooth" monicker.
Vacuole
A sac that is used to store food, enzymes, and other materials needed by a cell.

Assists in rigidity of plant cells.
Chloroplast
Organelles that capture light energy and convert it to chemical energy through photosynthesis.
Cell Wall
Thick, rigid, mesh of fibers that surrounds the outside of the plasma membrane.
Protects the cell and gives it support.
Plasma Membrane
A thin, flexible boundary between a cell and its environment that allows nutrients into the cell and allows waste and other products to leave the cell.
Centriole
Organelle that occurs in pairs and are important for cell division.
Cilia & Flagella
Projections from the cell surface that aid in locomotion and feeding.
Objective
I CAN identify the structure and function of the parts of typical eukaryotic cells.

I CAN compare and contrast structures of plant and animal cells
Main Idea
Eukaryotic cells contain organelles that allow the specialization and the separation of functions within the cell.
Exam Question Examples
Do Now
9/12/18
Answer the following question in 2-3 complete sentences (You do not have to write the question).
Describe the component of the plasma membrane that prevents water and other substances to freely enter the cell.
In a far away city called Grant City, the main export and production product is the steel
widget
. Everyone in the town has something to do with steel widget making and the entire town is designed to build and export widgets. The
town hall
has the instructions for widget making, widgets come in all shapes and sizes and any citizen of Grant can get the instructions and begin making their own widgets. Widgets are generally produced in
small shops
around the city, these small shops can be built by the
carpenter's union
(whose headquarters are in town hall).

After the widget is constructed, they are placed on
special carts
which can deliver the widget anywhere in the city. In order for a widget to be exported, the carts take the widget to the
postal office
, where the widgets are packaged and labeled for export. Sometimes widgets don't turn out right, and the "rejects" are sent to the
scrap yard
where they are broken down for parts or destroyed altogether. The town powers the widget shops and carts from a
hydraulic dam
that is in the city. The entire city is enclosed by a large wooden
fence
, only the postal trucks (and citizens with proper passports) are allowed outside the city.

Do Now

Answer the following on your Do Now page.
1. Which organelle is responsible for providing the energy for the cell?



2. Where is the genetic material located in an eukaryotic cell?
Mitochondria are responsible for converting carbohydrates into usable energy for the cell.
The nucleus contains the DNA in each eukaryotic cell.

Answer the following question on your Do Now sheet. When finished, open notes.
1. Which cell organelle is NOT found in animal cells?

a. mitochondria
b. ribosomes
c. cell wall
d. golgi apparatus


2. Which of the following statements is part of the cell theory?

a. Cells are composed mostly of empty space.
b. Cells are generally large enough for the unaided eye to see.
c. All cells are produced from existing cells.
d. Only animals are made up of cells.
What is the main difference between prokaryotic and eukaryotic cells?
Exam Question Examples
Lysosomes are organelles that contain enzymes. Which of the following is a function of lysosomes?
a. lysosomes build lipids, carbohydrates, and proteins
b. lysosomes package lipids, carbohydrates, and proteins.
c. lysosomes break down lipids, carbohydrates, and proteins.
d. lysosomes store lipids, carbohydrates, and proteins.
Objective
I CAN identify the structure and function of the parts of typical eukaryotic cells.

I CAN describe how cell organelles work together.
Main Idea
Eukaryotic cells contain organelles that allow the specialization and the separation of functions within the cell.
1. Proteins are assembled on ribosomes.
2. Some proteins complete their assembly on the rough endoplasmic reticulum.
3. Proteins are carried to the Golgi apparatus in vesicles.
4. The Golgi apparatus sorts and packages proteins.
5. Vesicles are shipped to their final destination.
Quick Check
In what structure are proteins transported to the golgi apparatus?
True or False.
All proteins that are packaged in the golgi apparatus are sent outside of the cell through the cell membrane.
Organelle Elections
Continue working on Organelle campaign materials.
REMEMBER: There are four components that need to be completed this week!
Campaign commercial (TV or radio)
Can begin posting in media gallery
Campaign flyers to distribute.
Can print, AirDrop, or place in Media Gallery
Mudslinging
Memes or can also be done using another commercial
Debate speech.
To be announced when this will take place.

A number of scientists made contributions to cell theory. Which scientist was the first to use a light microscope to observe cells in a slice of cork?
Bob is developing a model of a cell. He labels a central structure as the nucleus, and writes a caption that describes how DNA is kept inside the nucleus. What type of cell is Bob developing?
