Name ________________________________ Date _________ Concept Covered: Macromolecules Bellwork 10/18 #1 2-1 Name the four macromolecules especially important to life. What are the two main functions of lipids? RNA and DNA are which type of macromolecules? A sugar, a phosphate group and a nitrogen base form the building blocks of which macromolecule? Which macromolecule is needed as quick energy? Carbohydrate Lipids Proteins Nucleic Acids Take a moment to review Macromolecules and complete the questions WITHOUT your notes or textbook. Stores fat for long term energy use Insulates/Protect Stores fat for long term energy use Insulates/Protect Nucleic Acid Carbohydrates

Essential Question Agenda 10/18 Learning Goal How do cells function to make up living things? Review Discovery of cells/Cell Theory HW: Create a poster displaying the 3 parts of the cell theory Learning Goal Explain how the cell theory changed over time Compare the compound light microscope to the dissecting scope. Identify the differences between prokaryotes & eukaryotes. Identify the differences between plant & animal cells.

Discovery of the Cell Theory You will have about 20 minutes to Read section 3.1 in your text book. WRITE what each person did to contribute to discovering cells then, DRAW and COLOR a picture in each pane to represent what the scientists discovered.

Robert Hooke Viewed cork Named what he saw cells to resemble the jail cells

Anton van Leeuwenhoek Made better more powerful lenses for microscope Observed cells in greater detail 1st to view living things

Turn and Talk – Shoulder Partners When doing turn and talks these are quick! They should not take more than 10-20 seconds MAX. If you don’t know the answer, read off your notes. Then put your notes down and say it again without looking. Partners, make sure no one says the word “IT”! All students must use proper terminology to learn the material. Correct each other if mistakes are made. When finished with the question STOP TALKING and LOOK at the teacher.

Turn and Talk – shoulder partners High five your shoulder partner Determine who is Partner A and who is Partner B Partner A turn to Partner B and Explain what Robert Hooke did to contribute to the cell theory Partner B turn to Partner A and Explain what Anton Van Leeuwenhoek did to contribute to the cell theory Robert Hooked looked a cork under a microscope and decided to name what he saw cells after the jails cells Anton Van Leeuwenhoek made a higher power microscope and was the first person to view a living cell

Mathias Schleiden 1st to study plants Stated plants made of cells Called friends to share information

Theodor Schwann Noticed plants and animals had similarities Concluded all living things are made of cells

Rudolf Virchow Stated cells come from preexisiting cells NOT from spontaneous (random) generation

Turn and Talk – face partners High five your face partner Determine who is Partner A and who is Partner B Partner B turn to Partner A and Explain how Schleiden and Schwann contributed to the cell theory Partner A turn to Partner B and explain What did Rudolf Virchow do that was SO important for the cell theory? Schleiden studies plants and realized they were made of cells so he called his friend Schwann who was studying animals and realized they were made of cells too! Virchow is important because he realized that cells come from preexisting cells and that radically changed the idea of the time that they were created randomly

So what is the Cell Theory All organisms are made of _________ All existing cells are produced by other living _______ The ______ is the most basic unit of life Watch the following video and add to your notes! CELLS CELLS CELL https://youtu.be/FUqORLDDwVM

Exit ticket Answer the following question IN COMPLETE SENTENCES: How has the cell theory changed over time? Include people and what they did to contribute to the final theory. Write down any question you have from today’s lesson. Reminder: HW-cell theory poster due tomorrow!

Bellwork 10/19-20 Name ________________________________ Date _________ Concept Covered: Macromolecules #2 2-1 Amino acids are the building blocks of which class of macromolecules? 2. Nucleotides are the subunits of which class of 3. Polysaccharides are classified as Carbohydrates c. Lipids Proteins d. Nucleic Acids 4. Match the function of the macromolecules. Carbohydrates Lipids Proteins Nucleic Acids _____________ quick energy for cell activities _____________ speeds up chemical reactions _____________ stores genetic information _____________ structure (muscles) _____________ energy storage Take a moment to review Macromolecules and complete the questions WITHOUT your notes or textbook. PROTEINS NUCLEIC ACIDS carbohydrates Proteins-enzymes Nucleic acids proteins lipids

Let’s Review Cell Theory Review Organisms All ____________ are made of _________ All _________ cells are produced by other living _______ The ______ is the most basic unit of ________ Cells existing Cells Cell life

Cell Theory Review What does the cell theory say is true about a sea turtle and pine tree? Both are made of one or more cells Both have the same # of cells Both have tissues Both have the same type of cells

Cell Theory Review Which of the following is NOT a principle of the cell theory? A. All organisms are made of cells B. The cell is the most basic unit of life C. All cells come from spontaneous generation D. The existing cells are produced by other living cells

Essential Question Agenda 10/19-20 Learning Goal How do cells function to make up living things? Prokaryote vs. Eukaryote Video/Reading HW: Study over material covered this week to prepare for a quiz next week! Learning Goal Explain how the cell theory changed over time Compare the compound light microscope to the dissecting scope. Identify the differences between prokaryotes & eukaryotes. Identify the differences between plant & animal cells.

Main Types of Cells You have 10 minutes to Read page 73 and complete the Venn Diagram

Now watch the video and add to your notes 2 main types of cells: Prokaryotic and Eukaryotic https://www.youtube.com/watch?v=8IlzKri08kk&feature=youtu.be

2 main types of cells: Prokaryotic and Eukaryotic Does NOT have a nucleus or membrane bound organelles Single celled organism Has a nucleus and membrane-bound organelles Multicellular organisms Microscopic in size Enclosed in a membrane Contain cytoplasm Contain organelles RIBOSOMES

QUICK WRITE – 2 minutes Using what you have learned in class and given the following picture, identify each image as a prokaryote or eukaryote and explain why! Be specific and use and underline terms. Figure A Figure B

Share out Switch papers at your table Read what your tablemate wrote Write whether you agree or disagree with their response and WHY. BE SPECIFIC!

What do we think? Check yourself Figure A Figure B Figure A is a Eukaryotic cell because it has more organelles inside and is very complex. It also has only one cell boundary, a cell membrane Figure B is a Prokaryotic cell because it is much simpler than Figure B. There are not a lot of organelles inside of it and it has two boundaries around the cell, a cell wall and a cell membrane.
