Cell Membrane Homeostasis

If there is 5 percent water inside a cell and 5 percent water outside a cell

• more water will move inside the cell

• more water will move outside the cell

• There will be no movement of water cells

In this image, the cell is using which type of molecular transport?

• Osmosis

• Diffusion 

• Endocytosis

• Exocytosis 

Which of these types of transport are passive?

• Phagocytosis

• Diffusion

• Exocytosis

• Facilitated diffusion

When looking at the cell membrane, where are the phosphate heads located?

• Floating between bilayer levels

• Outer part of the bilayer

• Inner part of the bilayer

• Located at different parts throughout the bilayer

How is diffusion (left) different from the process on the right?

•  Diffusion takes place due to osmotic pressure. 

• Diffusion requires cellular energy for the transfer of molecules.

• Diffusion requires protein channels as a passage-way for particles

• Diffusion transfers particles from an area of high to low concentration. 

Permeable means

• things can pass through

• the concentration levels are different

• it is permanent

• things are stuck

What type of transport does not require energy? 

• Active Transport

• Passive Transport

The picture below is an example of _________________ .

• osmosis

• isotonic

• diffusion

• active transport

A type of active transport that releases particles that were enclosed from a cell when the membrane of the vesicle fuses with that of the cell membrane

• Exocytosis

• Osmosis

• Mitosis

• Endoyctosis

This is a ____.

• Golgi body

• plasma membrane

• lysosome

• cell wall
