Movement Through the Membrane Mr. Luis A. Velázquez Biology.
The Plasma Membrane. The cell membrane functions as a semi- permeable barrier: The cell membrane functions as a semi- permeable barrier: allows a few.
Opening Activity 11/3/15 Scientists refer to the cell membrane as a fluid mosaic model. What is a mosaic? (hint: the pictures below are mosaics)
Homeostasis and Cellular Transport. Cell Membrane A phospholipid bilayer that forms the outer membrane of a cell Is selectively permeable Controls which.
TODAY’S AGENDA P.O.D: Make an initial observation of the fish tank before the food coloring is added. Then predict what will happen when a fish tank filled.
1. What is the best way to float a thin metal pin on water? How come it works, although the pin is much more dense / heavier than the water? 2. When are.
Chapter 5 The Plasma Membrane. The Cell Membrane: OUTSIDE INSIDE HYDROPHILIC HEAD HYDROPHOBIC TAIL TRANSPORT PROTEIN.
Phospholipid Bilayer. The Cell Membrane a phospholipid bilayer.
Water booklet 1. Fold both pieces of paper hamburger-style On the first piece of paper, mark a 1 in from the folded edge.
The cell membrane is a phospholipid bilayer. Sometimes you will hear it referred to as a “fluid mosaic”.

Membranes Biology 11. Plasma Membrane: the outer boundary of a cell that encloses the cells contents.
THE CELL MEMBRANE The boundary of the cell is called the cell membrane . It is also called Plasma membrane.
Chapter 7: Cells. 1) Regulates what goes in and out (selectively permeable- some molecules too large or too strongly charged to cross while others.
Plasma Membrane: Structure & Function Objective 2.03: Maintenance of Homeostasis Movement Into & Out of the Cell.
Chapter 20 Water and pH. Chemistry of water Water is a POLAR molecule. This means it has covalent bonds that do not share electrons equally. The oxygen.
Cell Structure and Function Cell Boundaries. What Are We Learning? Benchmark: SC.912.L.14.2 –...Relate structure to function for the components of plant.
2.4.1 Draw and label a diagram to show the structure of membranes (1).
Chemistry of Life Properties of Water.
Introduction to Cell Transport and the Cell Membrane
Cell Membranes. PLO’s B9 - analyse the structure and function of the cell membrane Identify molecules in the membrane and how they contribute the characteristics.
Cell Membrane Outside of cell Inside (cytoplasm) Carbohydrate chains
The Cell Membrane Cell Biology standard 1a
AP Biology Why are we studying water? All life occurs in water All life occurs in water –inside & outside the cell.
Cell Membranes are composed of 2 Layers of Phospholipids = Phospholipid Bilayer 2 layers of phospholipids Heads = love water Tails = hate water Middle.
The Cell Membrane What does the cell membrane do? Separates living cell from aqueous environment Controls traffic in & out of the cell –allows.
Let’s look at one example involving osmosis. Osmosis is the diffusion of water across a semi permeable membrane such as a cell membrane. A semi permeable.
