1 Plant Transportation A closer look at xylem and phloem

2 Vascular Plants Vascular plants, like celery have a specialized system for transporting water and nutrients through their systems. Vascular plants, like celery have a specialized system for transporting water and nutrients through their systems. The stem of a plant has two main highways of transportation: xylem and phloem. The stem of a plant has two main highways of transportation: xylem and phloem.

3 How does a plant transport food, water and nutrients? Xylem The plant cells that move water and nutrients from the roots to the leaves. Phloem The plant cells that move food from the leaves to the rest of the plant.

4 Xylem is in the center Phloem is on the outer edge Xylem Phloem

5 Another Look Here you see a longitudinal view of the xylem in celery. Xylem

11 How does it work? 1. Water is collected by the roots, but how does it get up to the leaves where it is needed? 1. Water is collected by the roots, but how does it get up to the leaves where it is needed? 2. As the plant receives sunlight, water in the plant is evaporated and escapes the plant. 2. As the plant receives sunlight, water in the plant is evaporated and escapes the plant. 3. The plant must replace the water. The water that is evaporating at the top creates suction that helps water from the roots climb to the leaves through the xylem. 3. The plant must replace the water.

Water passes from cell to cell until it gets to where it is needed. 4. Water passes from cell to cell until it gets to where it is needed cross section view 3. Transpiration 4.
