Root Pressure And Transpiration

Question 1

What is root pressure?

Answer 1

It is when roots bring water and minerals into the xylem and there are to many minerals, so the plant uses osmosis to reduce the concentration difference of water and minerals.

Question 2

What is Transpiration?

Answer 2

When water is pulled up the stem against gravity. Root pressure helps. Causes water vapour in the leaves to exit through the stoma and the guard cells

Question 3

What is the effect of root pressure on water movement?

Answer 3

Root pressure causes more water to go up the leaf because of osmosis after the plant has gotten too many minerals

Question 4

What is the difference between root pressure and transpiration?

Answer 4

Root pressure pushes water into the plant from the roots, Transpiration pulls water up into the plant so that the water vapour in the leaves can exit through the stoma and guard cells

Question 5

What is Osmosis?

Answer 5

Osmosis is the movement of water from a high concentration to a low concentration

Question 6

What is diffusion?

Answer 6

Diffusion is the movement of something from high concentration to low concentration

Question 7

How does a plant go against the force of gravity to bring water up from their roots?

Answer 7

A plant uses root pressure and transpiration to push and pull the water throughout the plant.
