Okay, I see the matching section at the bottom of the worksheet. It asks to match the structure or function with the correct letter from the diagram. The functions listed are: "Attracts water", "Helps maintain flexibility of membrane", "Involved in cell-to-cell recognition", "Repels water", "Make up the bilayer", and "Help transport certain materials across the cell membrane". To correctly match these, I need to recall the properties of each component labeled in the diagram. For instance, "Attracts water" refers to the hydrophilic phosphate heads (G), while "Repels water" refers to the hydrophobic fatty acid tails (I). "Helps maintain flexibility" is a key function of cholesterol (H). "Involved in cell-to-cell recognition" is the role of glycoproteins (C) and glycolipids (E). "Make up the bilayer" is the phospholipid bilayer itself (A or F). "Help transport certain materials" refers to integral proteins (B). Now I will compile all this information to provide the final solution.
Final Solution
Here is the complete solution for the Cell Membrane Coloring Worksheet:
1. List 4 functions of the cell or plasma membrane:
a. Selective Permeability (controls what enters and leaves the cell)
b. Cell Signaling/Recognition (allows the cell to respond to its environment)
c. Maintaining Homeostasis (regulates the internal environment)
d. Structural Support & Protection (defines cell shape and protects internal components)
2. Correctly color code and identify the name for each part of the cell membrane:
*
Phospholipid bilayer (no color): Letter `A` or `F`
*
Integral protein (pink): Letter `B`
*
Fatty acid tails (orange): Letter `I`
*
Phosphate heads (yellow): Letter `G`
*
Peripheral protein (red): Letter `C` (Note: C is typically a glycoprotein, which is an integral protein with carbohydrates. A peripheral protein is usually attached to the surface. Based on the diagram, C might be mislabeled as a peripheral protein; it's more accurately a glycoprotein.)
*
Cholesterol (blue): Letter `H`
*
Glycoprotein (green): Letter `C`
*
Glycolipids (purple): Letter `E`
3. Match the cell membrane structure or its function with the correct letter:
*
Attracts water: `G` (Phosphate heads are hydrophilic)
*
Helps maintain flexibility of membrane: `H` (Cholesterol prevents the membrane from becoming too rigid)
*
Involved in cell-to-cell recognition: `C` or `E` (Glycoproteins and Glycolipids have carbohydrate chains that act as identification markers)
*
Repels water: `I` (Fatty acid tails are hydrophobic)
*
Make up the bilayer: `A` or `F` (The entire phospholipid bilayer)
*
Help transport certain materials across the cell membrane: `B` (Integral proteins form channels or carriers for transport)
