ON THE MOVE
THIS AND THAT
100
This allows some things to enter or leave cell and keeps other things outside or inside the cell
What is a SEMI or SELECTIVELY PERMEABLE CELL MEMBRANE?
100
Letting substances leave the cell by wrapping the cell membrane around it and releasing it FROM the cell
What is EXOCYTOSIS
200
This happens when molecules move away FROM an area where there are more of them TO an area where there are fewer of them
What is DIFFUSION
200
Taking substances into the cell by wrapping the cell membrane around it and absorbing it in
What is ENDOCYTOSIS
300
DIFFUSION is an example of this type of (movement)transport (hint: it's lazy)
What is PASSIVE TRANSPORT
300
Because sometimes larger molecules that can't go directly through the cell membrane or are too large for transport proteins need to be moved in or out
Why are ENDO and EXOCYTOSIS important ?
400
This type of diffusion involves transport proteins to help transport (move) molecules that are too big to pass through the cell membrane by themselves
What is FACILITATED DIFFUSION
400
Even gas particles (like perfume) can move into the atmosphere by this process
What is DIFFUSION
500
This type of transport (movement) requires ENERGY to move materials through the cell membrane
What is ACTIVE TRANSPORT
500
An example of THIS is when the cell needs to get rid of a foreign object like a bacteris or virus
What is ACTIVE TRANSPORT
