Objectives/Where does this fit Objective/Review   SWBAT describe the composition of the cellular membrane as it relates to cellular transport.

Homeostasis and the Cell Membrane? What is homeostasis? Homeostasis is the many processes that regulate our bodies to maintain balance and stability. Some examples?

So, the body must keep things equal. Let’s zoom into the cellular level. “Inner Life of Cells” video TWO observations on your notes http://multimedia.mcb.harvard.edu/

Cells… Cells are CONSTANTLY interacting with their environments. They have to exchange substances with the outside environment. They play a major role in maintaining our body’s homeostasis.

How do cells control what comes in and out of the cell?

Exit Ticket   The tendency of organisms to maintain a stable internal environment is called A. cellular organization B. homeostasis C. metabolism D. reproduction Which of these is an example of homeostasis in a multicellular organism? A. Inheriting a gene B. Growing larger and stronger C. Drinking an excessive amount of sugar water D. Regulating body temperature Which of these describe the primary function of cell membranes? A. They allow certain molecules to enter and exit the cell. B. They allow all molecules to enter and exit the cell. C. They do not allow molecules to enter nor exit the cell. D. They allow all molecules to enter the cell, but not exit it.   The phospholipids of the cell membrane have two components. Which of these parts is attracted to the water outside the cell and the water in the cytoplasm? A. hydrophilic heads B. protein channels C. hydrophobic tails D. protein receptors
