MOVMENT OF SUBSTANCES IN AND OUTof the cell

Question 1

what is diffusion

Answer 1

its the movment of particles from their higher cocencentration to their lower concentration down a concentration gradient

Question 2

osmosis

Answer 2

the movment of water molecules of water molecules from higher water potiential to low water potential through a partially permeable membrane

Question 3

factors affecting rate of movement

Answer 3

hugh tempreture will increcrease the rate of movment as there is more energy more kinetic energy so particles move faster
a high concentration gradient will increase rate of movment
a short diffusion distance will increase the rate of diffusion
large surface area to volume ratio will increase rate of movment as there is more area for the particles to move
