Cell Membrane and Transport Test Review

The cell membrane is made of what?

• Two layers of phospholipids with proteins

• Cytoplasmic fluid

• DNA

• Ribosomes

This image shows molecules inside and outside of a cell.

The image represents what?

• Osmosis

• Diffusion

• Active transport

• Carrier Proteins

Based on this image, if no energy is involved, what is happening?

• Osmosis

• Diffusion

• Facilitated Diffusion

• Active transport

What is shown in this image?

• Active transport

• Facilitated Diffusion

• Osmosis

• Diffusion

When there is no energy involved and non-polar particles move into or out of the cell (some can use channel proteins), this is known as what?

• Active transport

• Passive transport

• Osmosis

• Cell regeneration

Secretion from a cell, cellular excretion, or cellular export or materials are all terms that can be used to describe...

• Endocytosis

• Pinocytosis

• Phagocytosis

• Exocytosis

Looking at the Glycoprotein, we see that it has a carbohydrate chain on it. What is the function of a Glycoprotein?

• Identify what type of cell it is.

• Allow movement of molecules in and out of the cell

• Hold the DNA

• Fix any breaks in the membrane

Based on the image, how do we know this is diffusion?

• Going from Low to High Concentration

• Going from High to Low Concentration

• Uses energy to complete the process

• Moves very large polar particles

The salt in the glass of saltwater is considered the

• solvent
• solution 
• pepper
• solute

A freshwater plant is placed in a container of saltwater. What will most likely happen to the cells of the plant?

• They will swell because water will move into them
• They will swell because salt will move into them.
• They will shrink because water will move out of them.
• They will shrink because salt will move out of them
