“What factors can affect the rate of osmosis in plant cells?”
temperature
higher temperatures
can make the water molecules move faster
higher temperatures can increase the rate of osmosis
lower temperatures
low temperatures can decrease the rate of osmosis
can make the water molecules move slower
surface area
increased space for transport
A larger surface area provides more area for water molecules to diffuse through the semipermeable membrane, which increases the rate of osmosis.
surface area and volume ratio
Osmosis is often referred to in terms of the surface area to volume ratio. A higher ratio means a big surface area relative to the cell's volume, enabling more efficient water absorption.
pressure
turgor pressure
water pushes againist the ridid cell wall known as turgor opressure
builds up and opposes the osmotic movement of the water
affect on the rate
as the turgor pressure increses, it makes it harder for the water to enter the cell slowing dwn the rate of osmosis
exturnal pressure
lower pressure
Conversely, can create a pressure gradient, encouraging water to move into the cell.
higher pressure
When applied externally, can force water out of a cell, slowing down osmosis.
