Question

How is the phloem in a leaf related to the roots of the plant?

a. cells that contain sugar move between the leaf and roots within the phloem. 

b. chloroplasts that make sugar move through phloem cells to the roots. 

c. water in the phloem cells comes to the leaf from the roots. 

d. sugar made in the leaf is carried to the roots by cells in the phloem.

Answer 1

The phloem carries important sugars, organic compounds, and minerals around a plant. Sap within the phloem simply travels by diffusion between cells and works its way from leaves down to the roots with help from gravity. The phloem is made from cells called 'sieve-tube members' and 'companion cells'.
