1)Define prokaryote and provide an example of an organism that is a prokaryote.2)Define eukaryote and provide an example or a type of cell that is eukaryotic.

Eagle Zone- 8 minutes

Eagle Zone- 8 minutesCreate a Venn Diagram comparing and

contrasting the organelles of prokaryotes and eukaryotes.

The basic unit of life(smallest living unit)

The Cell

The student is expected to:(4a) Compare and contrast the structures of prokaryotic and eukaryotic cells(4c) Compare the structure of viruses to cells

Other science skills3b - The student uses critical thinking and scientific problem solving to make informed decisions. The student is expected to:(3F) research and describe the history of biology and contributions of scientists.

TEKS Science Concepts

Engage:

Describe what you see in this picture

The Amazing Cell (video)From shared drive

Contributing ScientistRobert HookeUsed a microscope to

examine cork (plant) Hooke called what he

saw "Cells"

Using the Microscope

Review for quiz10 minutes

only after the bell rings

Microscope parts AND functions

Using the Microscope

Choose 5 or more parts of the microscope to label

After you label the part, write the function of the part

Draw a line-place extra credit under the line

1 point for each extra part and function- max=5

Cellular DiscoveryUsing the lab sheets provided to you, FOLLOW DIRECTIONS to observe different types of plant, animal, and bacterial cells under the microscope and record your observations. Be sure to CLEAN YOUR SLIDES AND STATION THOROUGHLY WHEN YOU ARE DONE.

Tic- Tac- Toe Project (individual home project)You will be creating 3 small products for this project.Each product will have a grade of it’s own worth 100 points.The grades for each product will be averaged together for one total project grade. There is only one grade for this in the grade book- Not 3!

Internal Organization

Cells contain ORGANELLES.

Cell Components that PERFORM SPECIFIC FUNCTIONS FOR THE CELL.

The Nucleus

Brain of CellBordered by a porous

membrane - nuclear envelope.

Contains thin fibers of DNA and protein called Chromatin.

Rod Shaped Chromosomes

Contains a small round nucleolusproduces ribosomal RNA

which makes ribosomes.

Cellular Organelles

The cell membraneThe boundary of the

cell.MAINTAINS

HOMEOSTASISComposed of three

distinct layers.Two layers of fat

and one layer of protein.

Cytoplasm A solution made of many different types of molecules

Fills the cell“jelly” fluid

Found in plant, animal, and prokaryotic cells

Central Vacuole

Sacs that store food, wastes, and ions

Helps maintain cell TURGOR pressure

ONLY Found in plants and protists.

The Chloroplast

Double membraneCenter section

contains granaThylakoid (coins)

make up the grana.Stroma - gel-like

material surrounding grana

Found in plants and algae.

Cell Wall

Extra structure surrounding its plasma membrane in plants, algae, fungi, and bacteria.

Cellulose – PlantsChitin – FungiPeptidoglycan - Bacteria

CentriolesFound only in

animal cellsPaired organelles

found together near the nucleus, at right angles to each other.

Role in building cilia and flagella

Play a role in cellular reproduction

LysosomesRecycling Center

Recycle cellular debrisMembrane bound

organelle containing a variety of enzymes.

Internal pH is 5.Help digest food

particles inside or out side the cell.

Flagella

Prokaryote

Sperm

Whiplike tail used for locomotion (movement)

Enables single cells to swim

For cells attached to tissues (like our air passages), it moves liquid over the surface of a cell

Found in some bacteria and single celled eukaryotes

Mitochondria

Powerhouse of the cell

Breaks down sugar into usable energy

called ATPHas its own DNA

Cell membrane

Endoplasmicreticulum

Microtubule

Microfilament

Ribosomes Mitochondrion

Cytoskeleton Framework of the cell Small microfilaments

and larger microtubules. Gives cell its shape and

help with the movement of its organelles.

Golgi Body

A series of flattened sacs that modifies, packages, stores, and transports materials out of the cell.

Works with the ribosomes and Endoplasmic Reticulum.

Endoplasmic Reticulum—Rough and Smooth Complex

network of transport channels.

Two types: 1. Rough

a) contains ribosomes on its surface

b) releases newly made protein to golgi body.

2. Smootha) ribosome freeb) Used for cell

detoxification.

Ribosomes

Small non-membrane bound organelles.

Contain two sub unitsSite of protein

synthesis.Protein factory of the

cellEither free floating or

attached to the Endoplasmic Reticulum.

Mitochondrion

Double MembranousIt’s the size of a

bacteriumContains its own DNA;

mDNAProduces high energy

compound ATP

ElaborateArt Show

Create a drawing of a prokaryotic cell (bacteria) or a eukaryotic cell (plant or animal cell) to be displayed in the E! Art Gallery (hallway)

Include the following information with your drawing:Label at least 6 organelles found in that cell (do not

use nucleus , cell membrane, or cell wall)Provide the functions for the organelles you listedOn the bottom of your construction paper, explain

the difference between a prokaryotic cell and a eukaryotic cell.

Evaluate The students will draw and label both a

prokaryotic and a eukaryotic cell. Pass/Fail

The students will complete a Venn diagram comparing both prokaryotic and eukaryotic cells showing at least two differences.

The students will correctly match at least 10 organelles with their function, using the animal and plant cell model. (quiz and project)
