transportation in plants

Question 1

describe transportation of minerals and water in plant through root pressure.

Answer 1

root cells in contact with the soil take up ions. this creates a difference of concentration of ions between roots and soil. water moves into roots from soil to eliminate this difference which creates a steady column of water that is pushed up.

Question 2

describe transportation of minerals and water in plant through root pressure.

Answer 2

the loss of water from the plant creates a suction that pulls water from cells of roots.

Question 3

which form of transportation works on plants at night?

Answer 3

root pressure transportation.

Question 4

describe translocation.

Answer 4

1. sucrose moves into phloem tissue.
2. this movement increases osmotic pressure causing water to move into the phloem.
3. movement of water increases pressure which moves material in phloem to tissue with less pressure.
