(i) In Phloem food synthesized through photosynthesis is transported from the leaves to other parts of the plant. |
| (ii) In Xylem transport of material takes place through vessels and tracheids which are dead tissue. |
(ii) In Phloem transport of material takes place through sieve tubes and companion cells which are living cells. |
| (iii) In the xylem upward movement of water is produced by transpirational pull occurring due to the evaporation of water from the leaves | (iii) In Phloem material is transported due to the difference in osmotic pressure created using energy from ATP. |
