- Transport systems in plants
- Phloem Tubes: Transport food
- 1) Made of columns of living cells, with perforated end- plates to allow things to flow through
- 2) They transport food substances (mainly sugars) both up and down the stem
- The movement of food substances around the plant is known as transloaction
- Xylem Vessels: Take Water UP
- 1) Made of dead cells joined together end to end, with a lumen (hole) down the middle of the tube
- 3) Thick side walls are made of cellulose, they are strong and stiff which gives the plant extra support
- 2) They carry water and minerals from the roots up the shoot to the leaves in the transpiration stream
