Transports sucrose around the plant.
3 factors of translocation
Causes the stomata to open and evaporate the water so more water is taken up to replace it.
More air movement increases transpiration
Higher temperature speeds up the process.
A potometer measures translocation.
How to work out
Distance moved divided by time taken
Requires light energy
When water and mineral ions are transported through the plant
More air movement means transpiration increases
Transports sucrose around the plant
Contain sieve cells to transport substances.
Transports water and minerals through the plant
Lignified dead cells that has no cytoplasm which gives water space to move through.
Carbon dioxide + Water -> Glucose + Oxygen
