Question

Which of the following helps in the upward movement of water and dissolved minerals from the roots to the leaves through the stem?

Options

Answer 1

Transpiration

Transpiration is the loss of water through the stomata of leaves and other aerial parts of the plants in the form of water vapour. It provides a transpirational pull, which is responsible for the upward movement of water and dissolved minerals from the roots to the leaves through the stem.
