MOVMENT OF SUBSTANCES IN AND OUTof the cell Flashcards
1
Q
what is diffusion
A
its the movment of particles from their higher cocencentration to their lower concentration down a concentration gradient
2
Q
osmosis
A
the movment of water molecules of water molecules from higher water potiential to low water potential through a partially permeable membrane
3
Q
factors affecting rate of movement
A
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
