Today's Focus: Water Potential

Bell Question

1. Place your homework on the podium.

2. Open the Cell Tonicity Lab Data Sheet, given to you in Google Classroom and then, with your partners, do the following:

   1. 1. • Determine whether the extracellular fluid was hypertonic, hypotonic or isotonic for each sucrose solution

         • Determine the osmolarity (cell concentration) of potato cells

         • Determine the solute potential for each concentration given the following:

           • • The temperature of the solutions was 0 degrees celsius

         • Determine the water potential for each concentration assuming it was in an open container

Today's In-class Tasks

1. We will go over the data from our lab and discuss water potential and any other Unit 2 questions

Assignment(s):

1. Prepare for the Unit 2 assessment, to be given on Thursday,  10/9

Today's Focus: Cell Size/Plasma Membrane

Bell Question

1. Place your homework on the podium.

2. With your partners and discuss the answers to this Cell Size FRQ

   1. 1. • Students were using the formulas for the surface area and volume of a rectangular solid to model cells of different sizes and shapes. They produced the data shown in the table.

           • • Identify the rectangular solid that represents the cell with the smallest amount of plasma membrane per volume of cytoplasm.

             • Describe the relationship between the dimensions of the rectangular solids and their surface area-to-volume ratios.

             • Using the data from the model, evaluate the hypothesis that cells shaped like rectangular solids 1 and 2 are better suited for slow metabolism and the long‑term storage of energy‑containing molecules than are cells shaped like rectangular solids 4 and 5

             • Based on the trends shown in the data, explain why some rectangular cells include folds or projections in their plasma membranes.

.

Today's In-class Tasks

1. We will work with the Cell Organelle cards and review the functions of cell organelles.

2. We will then discuss the answers to the Bell Question and how they relate to the Cell Size Lab.

3. After discussing Cell Size we will do a manipulative activity with Cell Membranes

4. Any remaining time will be spent working on the homework

Assignment(s):

1. 1. Listen to the video lectures and complete the Guided Notes for Topics 6, 7 & 9 lectures, given in Google Classroom.

   2. Continue reading and taking notes on Chapter 4 and begin reading Chapter 5.

      1. • Use the  Unit 2 Understandings and Objectives Study Guide to help you with note-taking

Bell Question

1. Place your homework on the podium.

2. Take out your lab notebook and, using Image 1, write the title of the lab, objective of the lab and then draw the data table.

3. When finished take out your stack of organelle cards.

Today's In-class Tasks

1. We will conduct a cell size lab; I will discuss the procedures

2. While waiting for data, we will do an organelle card activity.

3. After students collect their final lab data, we will analyze the data and discuss conclusions

Assignment(s):

1. 1. If you did not complete the Topic 3 Guided Notes, please do so.

   2. Complete the Topic 4 Video Lecture and Guided Notes.

   3. Continue reading and taking notes on Chapter 4 and begin reading Chapter 5.

Today's Focus: Origins of Life & Cell Organelles

Bell Question

1. Please place your homework on the podium

2. You will be given 3 sheets of paper with 6 organelle cards on each.

   1. 1. • While I am scoring your homework, I want you to write down the main function of each organelle on the back of each card.

Today's In-class Tasks

1. Students will review their homework with the answer key.

2. I will begin class with a lecture scientific beliefs on the origins of cells.

3. We will then finish identifying organelle functions on the organelle cards

   • 1. • I have an activity to do with these cards when finished.

Assignment(s):
