Both question 16,17
Answers
16. 1. xylem tissue of the plant have interconnected vessels and tracheids of roots stems and leaves
2. they form continuous system of water conducting channels which reach all parts of plant
3. at root, cells in contact with the soil actively take up ions creating a difference in the concentration of these ions between the roots and soils( root pressure)
17. 1. there is another strategy used by plant to move water upward is xylem known as transpiration (loss of water from stomata)
2. the water which is lost through stomata is replaced by the water from The xylem vessel in the leaf.
3. the evaporation of the molecule molecule create section which pulls water from the xylem cells of the roots.
16) Transportation of water takes place with the help of xylem in plants
17)The mechanism that causes movement of water in plants are the hydrostatic or suction force
