- Water flow through plants
- PHLOEM
- Transports food
- Transports sugars made in leaves
- To growing regions (new shoots) needed to make new plant cells
- To storage organs (root tubes) of plant needed to provide energy store for winter
- Living tissue
- XYLEM
- Takes water up
- Moving water and mineral ions
- Carries from roots to stem and leaves
- Made of dead cells
- Why is transport important?
- All cells need sugar for respiration - provide materials for growth
- Mineral ions needed for production of proteins and other molecules within cells
- Water
- Photosynthesis, CO2 +H2O = sugar
- Needed to hold plant upright
- When cell has lot of water inside vacuole presses cytoplasm against cell wall
- Pressure gives support for young plants and structure of leaves
- PHLOEM
