|
Explain the process of diffusion
|
movement of particles from an area where their concentration is high to an area where their concentration is low
|
p.34
|
|
|
Describe how osmosis occurs
|
The cells of living organisms are surrounded by and filled with fluids that are made mostly of water. Then the diffusion of water through the cell membrane occurs called osmosis.
|
p.35
|
|
|
Compare passive transport with active transport
|
passive transport does not need to use energy while active transport does
|
p.36
|
|
|
Explain how large particles get into and out of cell
|
to get into a cell, the cell membrane surrounds a particle and encloses it in a vesicle
to get out of a cell, vesicles are formed at the endoplasmic reticulum or Golgi complex and carry the paricles to the cell membrane |

|
osmosis
|
the diffusion of water through the cell membrane
|
p.35
|
|
|
passive transport
|
the diifusion of particles through the proteins
|
p.36
|
|
|
active transport
|
the movemnt of particles through proteins against the normal direction of diffusion
|
p.36
|
|
|
endocytosis
|
the cell membrane surrounds a particle and encloses it in a vesicle
|
p.37
|
|
|
exocytosis
|
vesicles are formed at the endoplasmic reticulum or Golgi complex and carry the paricles to the cell membrane
|
p.37
|
|
|
During diffusion, how do particles move?
|
They move without using any energy.
|
p.34
|
|
|
How does a cell take in large particles? How does a cell expell large particles?
|
A cell takes in large particles when the cell membrane surrounds a particle and encloses it in a vesicle
A cell expells large particles when vesicles are formed at the endoplasmic reticulum or Golgi complex and carry the paricles to the cell membrane, then the cell membrane fuses with it and the cell would then release the particles into its enviroment. |
p.37
|
|
|
The transfer of glucose into a cell does not require ATP. What type of transport supplies a cell with glucose? Explain your answer.
|
passive transport- In passive transport, it does not require ATP or energy.
