5 min AGENDA DO NOW: KWL Chart Objective(s): SWBAT demonstrate knowledge about cells and prokaryotic vs. eukaryotic cells. SWBAT compare and contrast eukaryotic and prokaryotic cells. Tuesday, September 22 Learner Profile - Inquirers Enter the classroom silently and find your seat. 1.Take out pencils, HAWK card, and agenda. 2.Everything else gets put by the back wall 3.Write down homework (Finish entire packet) in your agenda. 4.Pass your agendas to the front 5.Do Now 6.Wait silently for instructions

STATEMENT OF INQUIRY: Interactions among environments allows organisms to create their own identity and form relationships with various communities in order to survive. IB TRAIT: INQUIRERS Statement of Inquiry/IB Trait

I.How are living things the same? II.What are cells? III.Prokaryotic vs. Eukaryotic IV.Guided Practice V.Independent Practice VI.Exit Ticket VII.Closing and Questions Cells “ By the help of microscopes, there is nothing so small, as to escape our inquiry.” – Robert Hooke

Think about this… What do these things have in common? They are all made of one or more cells!

Cells All living things are made of cells. Cells are the building blocks of living things – they are the smallest part of an organism. What are some examples of living things?

Cells Some organisms are unicellular. Tell your elbow partner what you think this means! - - They are only made of one cell. Some organisms are multicellular. Tell your elbow partner what you think this means! - They are made of more than one cell. What are all living things made of?

Prokaryotic vs. Eukaryotic prokaryotic eukaryotic We classify cells into two distinct types – prokaryotic and eukaryotic. Let’s pronounce these together – -Prokaryotic {Pro-care-e-ot-ic} -Eukaryotic {You-care-e-ot-ic}

Prokaryotic vs. Eukaryotic As a table group, you will read an article about prokaryotic and eukaryotic cells. One person will read each paragraph. You will alternate who reads. Read the entire article before taking notes. Do not write on your article. After 5 minutes, I will give you the next instructions. 5 min

Prokaryotic vs. Eukaryotic Now that you have finished reading the article about prokaryotic and eukaryotic cells – summarize the article to your elbow partner. As a table group, go back through the article and fill in the venn-diagram on your guided notes to compare and contrast prokaryotic and eukaryotic cells. 5 min

Prokaryotic vs. Eukaryotic Simple, single-celled organisms – unicellular Smaller than eukaryotic cells. No membranes around their organelles. NO NUCLEUS – genetic information (DNA) floats around the cell. Examples: bacteria and archaea. Mostly multicellular – some unicellular. Larger than prokaryotic cells. Membranes covering organelles. NUCLEUS inside a membrane – holds all the DNA for the cell. Examples: animals, plants, fungi, algae. Cells Both contain DNA

Prokaryotic Simple cell that does not have a membrane-bound nucleus or organelles. Unicellular Small Simple NO NUCLEUS Bacteria NOT animals or plants

Eukaryotic Cells that have a membrane- bound nucleus and other organelles. Multicellular – some unicellular Large Complex NUCLEUS Plants and animals NOT bacteria

What is the biggest difference between a prokaryotic cell and a eukaryotic cell? Stop and Jot

Multicellular Multicellular organisms, such as plants and animals, have various levels of organization within them. Individual cells perform specific functions but become dependent upon one another and work for the good of the entire organism.

Cells The first level is the cell. Example: blood cells

Tissues Next level is tissues. Tissues are made up of cells that are similar in structure and function and work together to perform a specific activity. Example: cardiac muscle tissue, nerve tissue, blood tissue.

Organs Next level is organs. Organs are made up of tissues that work together to perform a specific activity. Example: Heart

Organ System Next level is organ system. Organ systems are made up of organs that work together to perform a specific activity. Example: Circulatory system

Organism Next level is organism. Organisms are made up of organ systems that work together to perform a specific activity. Example: Humans

Guided Practice Let’s take a look at some different types of cells. When you see the picture, you will have about 30 seconds to decide if you think it is a prokaryotic cell or a eukaryotic cell and why. You will silently think about your answer and then write it down on the whiteboard to hold up. 15 min

Independent Practice There are four false statements on your paper. First, explain why the statement is false using complete sentences. Second, change the bolded, underlined word to a more correct word. At the bottom, create an analogy for cells. 12 min

Independent Practice Example: All prokaryotic cells are multicellular. This statement is false because prokaryotic cells consist of only one cell which means they cannot be multicellular. I would replace the underlined word with unicellular. 12 min
