Transport in the Phloem
This is the mechanism that transports sucrose and organic material through the phloem of the plant
These three main factors play a role in the cohesion-tension model
Transpiration, adhesion and cohesion
The process of osmosis acts between concentration gradients from a concentration of...
low to high
The phloem is a tissue that transports sugar from the leaves to the roots underground which is the opposite of the....
Xylem
Translocation always moves sucrose from a ____ to a _____
Source to a sink
This percentage of water is evaporated during transpiration
90%
This is the proper term for the diffusion of water molecules and particles across a membrane?
Osmosis
This connected the two bulbs in the diagram that was HAND DRAWN
glass tube
In both bulbs, this allows water to pass but does not allow sucrose to pass
Permeable membrane
Root pressure can approximately pull water ____ meters
10 meters
This is why water droplets on the edges of leaves result of Root Pressure evaporate?
They cannot evaporate because of the humidity being high and the transpiration
This is a model that explains how sugar moves from a source to a sink
Pressure flow model
The phloem has this type of pressure causing the the flow from source to sink
Positive
These are a some examples as to how transpiration is caused (only have to give one)
Dry air, heat, and wind
Finish the statement
When a water solution has a high concentration of solutes......
the concentration of water molecules is low
What colour would a green plant be
Green
During the formation of a fruit, the movement of sucrose by translocation causes this to happen
Slowing down of growth in other areas of the plant
Negative pressure creates a pull of _____ to replace the lost water
Water
This causes more volume to move in through osmosis
High amount of solutes in the xylem
Various sieve tubes can conduct this in opposite directions from different sources to sinks
Phloem sap
