|
Students should be able to explain how the structure of root hair cells, xylem and phloem are adapted to their functions. |
|
How are the following adapted to their functions: a) root hair cells, b) xylem, c) phloem? Hot-seating 'who am I?' Students are allocated one of the specialised cells and they are hot - seated and the other students have to guess what they are.
In groups build models of root hair cells, xylem, phloem with fact sheets to support (if needed) |
|
|
|
Students should be able to explain the effect of changing temperature, humidity, air movement and light intensity on the rate of transpiration. |
|
How does increasing temperature, humidity and light intensity affect the rate of transpiration? Show transpiration using potometer |
|
|
|
Students should be able to understand and use simple compound measures such as the rate of transpiration. |
|
|
|
|
|
Students should be able to translate information between graphical and numerical form |
|
|
|
|
|
Students should be able to plot and draw appropriate graphs, selecting appropriate scales for axes |
|
|
|
|
|
Students should be able to extract and interpret information from graphs, charts and tables. |
|
|
|
|
|
The roots, stem and leaves form a plant organ system for transport of substances around the plant. |
|
Which parts of the plant are involved in transporting substances? |
|
|
|
Students should be able to describe the process of transpiration and translocation, including the structure and function of the stomata. |
|
What are translocation and transpiration and how do they work? |
|
|
|
Root hair cells are adapted for the efficient uptake of water by osmosis, and mineral ions by active transport. |
|
What is the job of the root hair cells and how are they adapted to it? EW - Describe and explain the functions of the root hair cells, xylem and phloem and how they are specialised to do them. |
|
|
|
Xylem tissue transports water and mineral ions from the roots to the stems and leaves. It is composed of hollow tubes strengthened by lignin adapted for the transport of water in the transpiration stream. |
|
What is the role of xylem tissue and how is it adapted for it? |
|
|
|
The role of stomata and guard cells are to control gas exchange and water loss. |
|
What is the role of the stomata and guard cells? |
|
|
|
Phloem tissue transports dissolved sugars from the leaves to the rest of the plant for immediate use or storage. The movement of food molecules through phloem tissue is called translocation. |
|
What is the role of the phloem and what is the name of this process? |
|
|
|
Detailed structure of phloem tissue or the mechanism of transport is not required. |
