Transport in plants
This chapter explores the essential transport systems in plants, focusing on xylem for water and mineral transport and phloem for organic solute…
What you'll learn
- Outline the transport needs of plants and the fact that some mineral ions and organic compounds can be transported within plants dissolved in water.
- Draw, label and describe the overall structure of herbaceous dicotyledonous stems, roots and leaves using a light microscope.
- Draw the structure of the transport tissues xylem and phloem using the high-power lens of a light microscope.
- Explain the process of transpiration.
- Describe the adaptations of the leaves of xerophytic plants with the aid of annotated drawings.
- Explain how water moves across a leaf through the apoplast and symplast pathways.
- Relate the structure of xylem to its functions.
- Explain the movement of water up the xylem from root to leaf, including the roles of cohesion–tension and adhesion.
- Describe the transport of water from the soil to the root xylem through the apoplast and symplast pathways.
- Relate the structure of phloem to its functions.
- Explain that assimilates dissolved in water, such as sucrose and amino acids, move through phloem sieve tubes from sources to sinks.
- Explain mass flow in phloem sieve tubes down a hydrostatic pressure gradient from source to sink.
- Explain how companion cells transfer assimilates to phloem sieve tubes.
