Diffusion is the movement of particles from
an area of equilibrium to an area of high concentration.
an area of low concentration to an area of high concentration.
an area of high concentration to an area of low concentration.
all of the answers describe what occurs in diffusion.
Osmosis is the movement of ________ across a semi-permeable membrane.
food
energy (ATP)
oxygen
water
A high/steep concentration gradient means
diffusion will occur at a decreased rate
diffusion will occur at an increased rate
diffusion will occur at a constant rate
concentration gradient does not affect the rate of diffusion
Which is true about active transport?
Substances move from a high to low concentration
Substances move down the concentration gradient
Energy is required
No energy is required
Which is an example of osmosis?
water moving into the root cells of a plant
carbon dioxide moving into the leaf of a plant cell
oxygen moving into the bloodstream from the lungs
potassium ions moving in and out of an animal cell
