Plasma

What is the "big idea" of the fluid mosaic model of plasma membranes?

• the plasma membrane creates a specialized FLUID that looks like a MOSAIC.

• the plasma membrane is a MOSAIC.

• the fluid mosaic model is NOT related to the plasma membrane.

• a plasma membrane is a MOSAIC of components that move FREELY and FLUIDLY.

_______ regulates what enters and leaves a cell.  

• Cell Membrane

• Nucleus

• Mitochondria

• Cytoplasm

• protein

• nucleic acid

Identify cholesterol molecule

• structure a

• structure b

• structure h

• structure i

Identify a peripheral protein

• structure a

This image is an example of a phospholipid. Which part of a phospholipid is HYDROPHOBIC?

• the phosphate "head"

• the lipid "tails"

Which explains how the inside of a cell remains separate from its environment?

• Through the selective permeability of the plasma membrane

• Through active transport processes of the transport proteins

• Due to presence of the membrane bound organelles

• By building a Clash Royale-style defensive structure.

What is the definition of selective permeability?

• It is the property of the plasma membrane that allows it to control movement of substances into or out of the cell.

• It is the polar heads facing outside of cells.

• It moves needed substances or waste materials out of the plasma membrane.
