Specification
the need for transport systems in multicellular plants
the structure and function of the vascular system in the roots, stems and leaves of herbaceous dicotyledonous plants
the examination and drawing of stained sections of plant tissue to show the distribution of xylem and phloem
the dissection of stems, both longitudinally and transversely, and their examination to demonstrate the position and structure of xylem vessels
the process of transpiration and the environmental factors that affect transpiration rate
practical investigations to estimate transpiration rates
the transport of water into the plant, through the plant and to the air surrounding the leaves
adaptations of plants to the availability of water in their environment
the mechanism of translocation

Add the words:
Cohesion
Osmosis
Adhesion
Transpiration
Stomata

The XYLEM transports ___________________ through ________________ transport.
The PHLOEM transports _________________ through ______________ transport (_____________________)

To each add: where in the plant is the sample from?
Xylem and Phloem, anything else

Why do plants need a transport system?

What practical method can be used to investigate transpiration rate?

Add labels: stem, root, leaf, xylem, phloem, root hair, cambium, vein/vascular bundle

State what kind of vessel, and add as many labels about the structure as you can
Describe how these structures are adapted for their function

Factor	How this may affect transpiration
Number of leaves
Number, size and position of stomata
Presence of cuticle
Light
Temperature
Relative humidity
Air movement/wind
Water availability

What are xerophytes?
Give an example of a xerophyte:
List some ways in which xerophytes are adapted to suit their environment.
Add labels to this cross section

Draw the three water transport pathways in 3 colours
Symplast pathway
Apoplast pathway
Vacuolar pathway
This diagram shows how water travels through a leaf.
1. What pathway is this?
2. Add labels

___________
gradient

Water leaves to:

This process is called:

SOURCE: ______ water potential, _______ pressure

This process is called:
