Today's Focus: Cell Size/Plasma Membrane

Bell Question

1. We will start with a cell organelle activity, please take out your Cell organelle and Functions card and cut them out.

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 discuss the answers to the Bell Question and then review the data from the lab.

2. We will then discuss the 2.3 Lecture Notes and answers to the homework

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