define plasmolysis

# data[].attributes.body
The movement of ions from higher water potential to lower water potential . Ans3-  Plasmolysis is the process of the channels opening and closing to through

# data[].attributes.body
Adenosine tri phosphate.
Ans4- diffusion

# data[].attributes.body
As the ions move from a lower concentration to higher concentration with the help of ATP (energy)

# data[].attributes.body
1)It needs energy so that ions can travel
from a lower concentration to a higher concentration.
2) Adenosine Tri Phosphate
3) The movement of ions from higher to lower concentration.
4)
5) -Temperature

# data[].attributes.body
Can also affect the rate of diffusion because the smaller the particals the faster the molecules diffuse FgPlaActive transport needs energy because ions are travelling against the concentration gradient .
Adnocin tri phosphate.
The movement of water molecules from higher concentration to lower concentration of ions is called  osmosis
Diffusion is affected by temperature as the temperature increases the molecules collide harder to the walls as a  result of which the rate of diffusion increases.
The surface area

# data[].attributes.body
Because it has to travel from lower to higher concentration which is travelling against the concentration
ATP-adenosine tri phosphate
water molecules travel from Higher potential to lower potential of water
temperature increases the molecules move faster and collide and start pushing the walls of the object .
Surface area-it is because there is more aerea on which pressure can act.

# data[].attributes.body
1)Because they move against the concentration gradient therefore they require energy
2) Adenosine Triphosphate
3) it is the movement of water molecule from higher potential to lower potential of water
4) loss of water
5) due to increase in temperature the molecules move faster and they start pushing themselves out of the wall
When the surface area increases the pressure acts more

1. Why does Active transport need energy ?
