Rates Of Diffusion Osmosis and Active Transport Flashcards
What are the three things that can affect the rates of Diffusion Osmosis and Active transport?
Temperature, concentration gradient , surface area to volume ratio
How is active transport different to Diffusion?
It goes from an area of ow concentration to high concentration.
What does active transport use?
It uses energy(ATP)
What is the definition for diffusion?
Where particles move from an area of high concentration to a low area of concentration?
What is the definition for osmosis?
The process where water molecules move across to a partially permeable membrane from an area of high water potential to an area of low water potential.
What type of organism would have a more surface area to volume ratio?A single celled organism or a Multicellular organism?
A single celled organism
What type of organism would have a more surface area to volume ratio?A single celled organism or a Multicellular organism?
A single celled organism
